In order to calculate certain foam systems, a Darcy-Weisbach calculation must be done, as opposed to a Hazen-William one. This was touched on in this older blog post: Darcy-Weisbach Who?
The following are numbers found in the technical data sheets of a particular brand of foam concentrate. Notes are added to illustrate which numbers go where.
Say you want to have European Standard fittings selectable in HydraCALC. You pick Utilities / Alter Pipe and Fittings to bring up the pipe tables and see they are already created, but you wonder why they don't show up.
The reason is there is no Short Name assigned to them. HydraCALC does not have every fitting immediately accessible from the input screen because that would bring up too many choices for you to sort through.
Assigning Short Names is easy. There are two rules:
I suggest using names that are indicative of the fitting name, for ease of recognition. These would be my choices for the EN fittings:
Once you pick OK on the fitting input screen, these values will be recorded and your fittings will now show up for the corresponding diameters when you right-click in the Fitting column.
A customer sent a job over looking for an explanation:
"I have an inquiry about HydraCALC. I’m trying to calculate a system with sloping branch-lines as shown in below figure. I made two calculations in which everything is the same except for the elevation.
First, all heads have same elevation of 20 feet. And second, each are provided exact elevation as shown below. My questions are the following:
The answer lies in the very question.
This is the system:
These are the results:
All elevations entered as 20':
All elevations entered as actual:
My answer (reader comments welcome):
Each system is getting enough pressure to supply water to 20’ of elevation for every head. In the case where all heads are labelled as 20’, this results in less flow and pressure as the system is more evenly ‘balanced’ from head to head.
In the system where the elevations vary, there is more ‘overage’ due to that fact that every head is getting 20’ of elevation pressure because the water has to be able to make it up to the highest head. This means even the 16’ and 17’ heads are getting 20’ worth of pressure. This is why NFPA 13 added the rule a while back requiring that the actual elevation at each head be entered – because it makes a negative impact on the calculation.
A side note: Back when this rule was implemented (Late 80s? Early 90s?), a good customer called me because he recalculated his sloping system using the new rules and it didn't work. My answer was - "That is why they added the rule!"
Many of our users aren't aware of the fact they can customize the cover sheet logo in HydraCALC. These steps are pretty easy and can normally be done in about 5 minutes.
1. You'll need your logo, preferably as a .BMP and with a resolution of 500x500 pixels or greater, but any image type will do.
2. Open your image file using Microsoft Paint. Check the pixel size of your canvas; you're trying to get to as close to a square image as possible. You can click the grips at the edges of your canvas to adjust it as necessary.
3. In the image above, the canvas is exactly 500 x 500 pixels. Make sure to leave some white space near the top, this means your image will be closer to the bottom, not centered inside the canvas.
4. When ready, save the image as a .BMP file. When you click 'Save as...', select the option 24-bit Bitmap (*.bmp)
Save the file to this folder [local drive]:\HES\HydraCALC\Ver50\Data\Setup\Reports and use the filename yourCompanyName
5. Using Windows File Explorer, browse to the location [local drive]:\HES\HydraCALC\Ver50\Data\Setup\Reports and locate a file called BLANK.DAT. Make a copy of it then rename it to yourCompanyName.DAT
6. You can check your logo by going to HydraCALC, then go to File|Print Final. When HydraVIEW opens, in the Cover Sheet drop down, you'll see your newly created logo in the list.
7. If you feel some adjustments are necessary, you can click on Tools|Page Setup then adjust the values in the Cover Sheet Graphics area in regards to the Tab, Width & Height. The tab value pushes the image from the left to the right, and your width and height are a ratio of your image's width and height.
Good luck and get in touch if you need any clarification.
From a customer today:
Question: Is it possible to set up separate databases for HydraLIST so that I can have part numbers that match up to the Supplier part nos.? I Know HydraLIST has alternate part-no options but I think it might be easier if I just set up a different database?
We primarily use 4 suppliers-
Viking Supplynet
Ferguson Fire
Core & Main (A/K/A HD Supply)
Fox Sprinkler
Answer, from Paul McKenna here at Hydratec:
You can create separate databases for each supplier -
1. Open Explorer or My Computer and go to the Hes\Hydlist\Ver50\data folder
2. Copy the SetUp folder 4 times and paste them in to the original Hes\Hydlist\Ver50\data folder
3. Rename the copied folders
SetUp-CoreAndMain
SetUp-Ferguson
SetUp-Fox
SetUp-Viking
You should end up the five folders names that start with SetUp
Inside HydraLIST you can switch from one vendor to another.
5. Pick the Utilities Pull down menu and select Switch General Data Location:
Click on Data folder in the tree. Pick on the folder you want to use
For this example we will pick on SetUp-Viking and pick OK
If you pick the Reset Default button the path will be setback to the original path to the original SetUp folder
You will get a message that lets you know that you are switching the data location. Pick OK
If you hover over the General Data Icon a tool tip will tell you which database you are currently using:
From here you can decide what needs to be done to each database. Contact us before you spend a lot of this altering the data in the folder, as there are preferred methods of altering the data in each folder.
With HydraCAD v56 for AutoCAD 2019 and updates for HydraCAD v54 and v55 due to be released soon, this would be a good time to revisit backing up your workspace. A common reason some of our users decide to hold off on running a HydraCAD update is due to the fact they'll end up losing their toolbar positions in their AutoCAD work area. This is your 'workspace', and with this blog post we'll cover saving and recovering it. Near the bottom of this post you'll see steps on sharing workspaces between computers and pulling a workspace from an older AutoCAD into a new AutoCAD.
AutoCAD's Customization Menu, the toolbar along the bottom right of your screen with a LOT of buttons, should have a gear icon, this is for your Workspace Settings. If you cannot see the gear icon, click the hamburger icon at the far right then turn on the Workspace Switching option. You can also turn on the Workspaces toolbar, found in the Acad group of toolbars.
SAVE YOUR WORKSPACE
Before anything, we must save your configuration. Select 'Save Current As...' from the list (or type in WSSAVE at the command prompt) and type in a name for the workspace. If you've already saved one, select it from the list to overwrite it with a new one. Personally, I like to use the current date so I'll remember the last time I backed up my workspace, but whatever you decide is up to you.
You can confirm it was saved by selecting the list of workspaces as you'll now see it as an option .
RUN THE UPDATE
At this point you'll run the HydraCAD update. At its conclusion, you'll notice your toolbars have realigned themselves to their default locations and your workspace is no longer in the list of saved workspaces.
RECOVER THE WORKSPACE
See the image below for help with steps 2 through 5.
1. From the workspace drop-down menu (shown in the image above), Select Customize.
2. In the Customize User Interface window, select the Transfer tab (a), then the Open button (b) on the right side.
3. Depending on your version of AutoCAD/HydraCAD, you will navigate to one of the following folders;
Acad 2015-2016 HydraCADv53 -\HES\HydraCAD\Ver50\Programs\Version53\Backup
Acad 2017 HydraCADv54 -\HES\HydraCAD\Ver50\Programs\Version54\Backup
Acad 2018 HydraCADv55 -\HES\HydraCAD\Ver50\Programs\Version55\Backup
Acad 2019 HydraCADv56 -\HES\HydraCAD\Ver50\Programs\Version56\Backup
4. You'll find a sub-folder based on the date and time of when you ran your backup. Double-click it then double-click 'HCADWIN.CUIX'.
5. On the right pane, you will see your previously saved workspace in the list. Click and drag it from the right to the left pane where it says 'Workspaces'.
6. Click OK in the Customize User Interface window to return to the drawing and a command prompt. You'll now see your saved workspace has returned to the list.
SHARING WORKSPACES
You can use this method to copy a workspace from one computer to another; the file you'll be looking for is HCADWIN.CUIX, use the one found under \HES\HydraCAD\Ver50\Programs\Version5_\ and your least intrusive method is to copy it to the desktop of the new computer and browse to that location when going through the transfer process. Delete the file from your desktop when complete.
INSTALLING A NEW VERSION OF AUTOCAD
This method should work fine between versions of AutoCAD as well (as long as the AutoCADs don't have too many years between them). When installing a new AutoCAD, always remember to NOT migrate your settings over. When the Acad and Hcad installs are complete, you'll use the steps above to transfer your older version Acad workspace over to your newer version Acad workspaces.
From a customer: Can I AutoList a plug at top of this tee?
From my co-worker Bill - yes you can:
This will list the correct tee at the end of the riser nipple and will list the plug with the miscellaneous material.
1. Insert a sprinkler head block defined as “directly connected” at the riser nipple
2. We often use Head5 for this purpose because of how it looks
3a. Define the PLUG/sprinkler as “point down” and “at bottom” if the plug is at the bottom of the riser nipple. Note: use at Bottom - if the 1’-6” long pipe is lower than the 2’-3 ½” pipe in our example
3b. Select Choose 3D Head Block and select Plug1 as the 3D representation
4. Scale the plug/sprinkler block down a bit so you can tell it is there, but not so large as a sprinkler block
My co-worker Paul produced this blurb, on request from a customer who was attempting a Velocity Pressure calculation (a velocity pressure calculation is required by NFPA when designing Fixed Spray deluge systems). This type of calculation requires the use of the Input Types field, discussed in this post a ways back: Why Use Input Types?
For this kind of calc, The program needs to know which pipes are perpendicular at pipe intersections. The perpendicular pipe is where the velocity pressure is used to determine the flow into the pipe.
You can use any of the default Input Types from in the selection box, in this example we have used the Letters A B & C as the Input Types for clarity
All of the pipe where the flow goes straight through must have the same Input Type. Outlet pipes where the flow is determined by the velocity pressure must have a different Input Type.
In addition to the perpendicular pipe outlets the velocity pressure is also used to determine the flow at a K-Factor where a sprinkler head is directly connected to a pipe. (The sprinkler is the perpendicular outlet).
We used A for the Input Type from the remote sprinkler back to the supply point. We used Input Type B for the pipe that comes off perpendicular to the Input Type A pipes and Input type C for the pipe that comes off perpendicular to the Input Type B pipes.
Based on this, the program knows where all the perpendicular pipe locations are and can calculate the velocity pressures correctly.
Below is a flow diagram showing all of the B Input Type Pipe Marked in Yellow and all of the C input Type Pipe Marked in Pink. The pipe not highlighted is Input Type A pipe.
The Velocity calculation is performed at the intersection of the different Input Types and the K-factor location.
This link will get you the example job used for this post. We suggest you place it in your \HES\HydraCALC\Ver50\Data\Jobs\Example Jobs folder. Velocity Pressure.WXF
Illustration for labeling Input Types
From a customer a little while back:
Q: I would like the head guide to have an option to spot the head based on the last one (with Ortho on so they line up). Kind of like the insert multiple sprinklers Or add the option to the “insert multiple” where you can access the head guide. I am using the custom guide to layout heads in an attic and am having a hard time getting them to line up.
A: This one took me a little bit to figure out. Changing the program for Head Guide is problematic, since we are taking advantage of a specific feature available inside AutoCAD - one that I won't bore you with, but is not used very often by drafters, if ever. Because if the way it works, we can't just make it do other things while running it. There is, however, another way to achieve what this custom wants as a result. And that means activating a command before running Head Guide. That command is SNAP (not, OSNAP). Setting the SNAP point will make the cross-hairs move in an Ortho-like motion. We already have a command to automate this - Align Crosshairs with Ceiling.
This is the room. We can use a head guide to run a line of heads up the middle:
Pick Align Crosshairs with Ceiling on the Sprinkler Toolbar.
Picking this will ask you to select a base point. Select a corner of the room, or even the midpoint of the lower leg
The cross-hairs will now jump in 1 foot increments as you move them. This will work, but it may be a little too 'jiggly' for some. To change the SNAP increment, type in SNAP at the command prompt and type in the desired increment. 2' would probably be best for most situations. But, if you have specific spacing requirements, you could set it to that. A reminder - SNAP can be toggled on and off with the F9 key.
Pick on of the four Head Guide commands. i am using the first one, the Standard guide.
Now, hover the Head Guide over the insertion point of the first head. Then, left click and insert the head.
Next, move the cross-hairs up to the next insert point and left click again, until you have your heads spotted.
Remember, hit F9 to turn off SNAP or pick Align Crosshairs with Ceiling again. That will turn off SNAP before prompting you to pick another insertion point to align.
ustomer from Sweden asked the following this week:
"I have a question about HydraCALC, is there a way to change the default path for where the program initially finds its projects to open?
For instance, now when I press OPEN, it always open “C:\HES\HydraCALC\Ver50\Data\Jobs”, we have our projects in a different location, so for me it would be nice if I could change the default location into our project folder."
The way to do this is through the desktop shortcut for HydraCALC. Right-click on the shortcut and pick Copy. Then right-click somewhere on your desktop and pick Paste. This will give you a second shortcut to work with, while preserving the original one,
Right-click on the shortcut and pick Properties. Then, pick the Shortcut Tab. Notice the Start in: field. That tells HydraCALC where to look for Jobs when you open or save one.
Change the Start in: field to be the location you want. Pick OK
Right-click again on the shortcut and pick Rename. Give the shortcut an appropriate name, so you can find it next time.
You can make as many shortcuts as you like, setting each one to a different job location. The same goes for HydraLIST and HydraCAD.
Want to make your own symbols? Easy
Want to use the same symbol for two different temperature heads? Easy
The answers all come down to the same thing. The second one albeit a little differently. And...a trick concerning the word 'same'
The answer is to start with an existing HydraCAD head, making changes to it (or not) and saving it.
HydraCAD heads are stored in the \HES\HydraCAD\Ver50\Programs\heads folder by default. (you can specify a central location as well per this post: Specify a Central Location for Sprinkler Heads)
To make a new symbol follow these easy steps
Example - Making a new head symbol
1. Open HEAD7
2. Immediately SaveAs HEAD30 (immediately, so that you don't save over the original)
3. Make Changes to head, as desired and Save it
The 'trick' concerning wanting to use the same symbol for two like heads, but of different temperatures is as follows:
Example - Using the same symbol for two different temperature heads
1. Open HEAD7
2. Immediately SaveAs HEAD7A
That's it! When you are defining sprinkler heads, just define one as 165º and the other as 212º (or whatever)
From a customer in Indiana:
Q: Over the past few years we have added several items to our database and many of the items require a long description. I have tried to abbreviate as much as I can but I am unable to get the description small enough to fit in the “Item” description box in HydraLIST. Is there any way of getting this to be more than 30 characters long. Thanks for all you help.
A: From co-worker Paul McKenna - We have had a long description in HydraLIST for some time now although most people do not use them
You must be in the General Data section where you alter the data associated with HydraLIST. In there, pick P/N Table
The items that have long descriptions will have the description highlighted in orange.
The long description is accessed by right clicking on the fitting description.
Enter the long description and pick OK to save the description. Pick cancel to return to the P/N Table without saving. Pick Delete to remove the long description and return to the P/N table. Pick Audit to eliminate long descriptions that are in the long description file but have not entries in the P/N table. Long descriptions can be added to the database when picking sprinklers for the Head Selector or Valves for the Valve selector by answering ‘Yes’ when prompted when collecting data.
Long Descriptions are included in the data when exporting or importing data in the P/N table. You will see the Long Description when you print out the Raw Materials List
A customer asked last week: How do I properly use a 4x3 Bell Reducer so that it lists correctly?
The answer, according to my co-worker Bill McKenna:
1. A coupling should already be on the pipe intersection where the diameters are changing
2. Select the coupling type required for the Bell Reducer being used:
The Diameter selected at right will fill in the ? mark - IE picking 4" will complete the 4 x 3 Reducers
3. Use Single Coupling to insert the Bell Reducer
Select the SMALLER diameter pipe for the insert. A coupling should already be on the pipe intersection where the diameters are changing. The command will break the pipe selected and add a block representing the reducer and a coupling.
Result: An OVERRIDE block will also be inserted. The 0'-3" long pipe inside the reducer will not be included in the stocklist created by AutoList.
Note: The diameter found in the reducer should be the larger of the two sizes. The point of the reducer should always be towards the smaller diameter pipe.
In HydraLIST:
From a Customer, via a co-worker:
I have a quick question. How to I list 001 Victaulic 90’s and 009 Victaulic Couplings? Is there an equivalent? I cannot seem to locate them in HydraLIST
The answer depends on which program is being used:
For AutoList in HydraCAD:
Change your fitting mapping to one of the available Firelock Fitting with 009 Coupling Groups - that's all it takes
For HydraLIST:
All of the part numbers for these fittings are included in the standard part number database.
In the MISC Input - key in 009 or 26F Firelock Fittings into the Search field and pick FIND to display all the fittings. Enter quantities and select Clean Up when done to remove those items that are not quantified
You buy an Autodesk Subscription, but are stymied when trying to install it on a user's machine? Yeah, so are a lot of people. Autodesk does not do a good job of explaining how user access works, IMHO.
Here is a typical scenario:
ABC Sprinkler Company buys two AEC Industry Collections. Johnny B. is the Contract Manager. He got that designation by being the one who ordered the software or who we understood to be the one who is going to handle the deployment of the software. He downloads the software from Autodesk Account and puts the install files on the company server. He then tells Bobby D. to install it. Bobby does so, but cannot actually use the software because he is told...
Contact your administrator to request permission to use this product.
...when he tries to use it. What happened?
This page from Autodesk explains it a bit, but i will try to go further than that.
Why did it fail?
Because each user must be specifically and explicitly given access to each product they are expected to use.
Why does Autodesk do this?
Because without user access being specified, users would be able to 'hoard' as many products as are available (i.e. AutoCAD, Revit, Navisworks), possibly leaving those that really need it out in the cold.
What must be done?
User Access must be granted. This is done by the Contract Manager. They must log into their Autodesk Account and give the users access
1. On the left, notice the Users item. Pick Users:
2. A list of users will appear:
3. Pick Edit Access for the user you are working with. Check the Assign box for all products you want to give them access to
4. Pick Save. In a few moments the User screen will update with the Products and Services showing the number of programs they can access
Now, the user will be authorized to use those seats. They must log in with their own Autodesk Account information in order to get that authorization.
There are many ways of adding loose material and kits to a HydraCAD drawing in order to get them listed. Some are old(er) and many are newer. All of these are on the Listing Toolbar. These do not need to be attached to pipes or sprinkler heads in order to have them list. They simply need to be inserted within the system boundary you are using (if one) on your drawing.
The first one of these is the Add Loose Material (2DS) command found on the fly-out associated with the fifth button on the Listing toolbar.
This command includes a diversity of items, of which three are listable:
Victaulic Master Details
These details were furnished by the Victaulic Corporation. They include a library all their water supply and fire sprinkler valves and fittings. Insert these as needed into the drawing. Please note - these details will not be picked up by the AutoList command
Loose Fittings
This command opens up a drawing containing many individual valves and fittings. These are AutoList ready. Simply copy and paste them from the opened drawing into your drawing, or right-click and drag and drop them from here to there.
Miscellaneous Fittings
Opens up a different drawing, from which items can be copied and pasted exactly like the Loose Fitting command above. However, unlike the Loose Fittings command, these are not graphic details, but blocks containing text.
These 'details' are notable in that they:
Take a look at the upper left of the Misc-Items drawing:
Double click on the PIPE GREASE item, below
Note the DESCription and the Part Number (P/N) (and SIZE). If you were to look at the data in HydraLIST, you would find this part listed under that number.
Again, select the items you want to list and copy and paste (or drag and drop) into your drawing to have them listed.
Note: You can make your own additions to this archive of items by copying and pasting any one of the text/blocks to another location in the Misc-Items drawing. Then, just double click and change the settings to something you want to list, keeping in mind that the P/N is how it finds the items in HydraLIST, not the description.
Looking at the right side of the Misc-items drawing, you will notice not individual items, but kits.
Likewise, these work just like the individual items at left (and described just above) but they correspond to kits or assemblies of items, also defined in HydraLIST.
2D Risers
This is an older command, but one that works like the above two commands. It contains risers that are pre-built for both Imperial and Metric unit systems, Wet and Dry. This command has largely been superseded by the 3D Riser tools found in the toolbar of the same name.
Again, copy and paste, or drag and drop these in your drawing.
