Sometimes Image2PDF doesn't register properly the first time you use it after reinstalling the software. If it continues to not work after the initial use, contact tech support.
The effect of the CV Time (closing time for CV) is generally opposite of the closing time for a control valve. Normally the longer it takes to close the CV the higher the pressure surge. This is because the reverse velocity is larger the longer the CV takes to close. The higher reverse velocity causes a larger pressure spike when the CV fully closes. This is not always the case because other factors are involved. However, a rapid closure for a CV is generally better.
When protecting a pipeline from a pump trip where there is a very rapid pressure drop using even a short time delay in the response of an air valve could allow a significantly larger pressure drop than if this is ignored. Air valve manufacturers do not provide time delay data so the time delay is generally set to 0. Providing for this input allows the user to evaluate the effect of a time delay.
Yes, but the following steps are required to enable the software to run properly.
- Extract files
- Copy the setup file to a local drive
- Browse to the location of this file
- Right click on it and select Properties
- Click on the Compatibility tab
- Check the box which says “Run in compatibility mode for” and select Windows XP Service Pack 2
- Click Apply and Ok
- Re-run the setup application
Option 1 - Access to WaterCAD software:
Option 2 - No access to WaterCAD software.
|EPANET will not accept pipe names and node names longer than 8 characters. Watercad has very few restrictions on naming so when you convert the Watercad file to EPANET there is an option to use Element Labels or Element IDs. If none of your pipe or node Labels exceed the 8 character limit then using the Element Labels is acceptable. However, if the names exceed 8 characters the conversion will truncate the names and numerous pipes and nodes will have the same name. Element IDs are assigned numbers. Opting to use them will make the number IDs the pipe or node name in the converted file.|
Open one file and select the entire system (or the part you want to copy) - use group box to do this. Under Edit (main menu) select Copy. Close the first model and open up the second model. Under Edit select Paste. If they are in the same coordinate system then the first system will be added in the correct location. If not you can drag it to the correct location. Duplicate node/pipe names will be automatically fixed.
A pipe is a connection between 2 nodes. Within a single pipe, multiple intermediate nodes (valves, hydrants, directional changes) are allowed. However, a change in diameter or roughness creates a new pipe. Also inserting an "end" node (pumps, tanks, active valves, regulators) creates a new pipe.
In demo mode, Surge will read, write, save and analyze models within the following limits: less than or equal to 10 pipes, 6"/150mm diameter, 1000'/300m length, one pump, active valve, and surge device each. Using the "Demo" shortcut, the following model limits apply for read, write, save and analyze: KYPipe - 50 pipes, Gas, Steam, GoFlow, SWMM - 30 pipes. Surge is read-only for 11-30 pipes. For unlicensed versions, or if the license key cannot
If you are running Google Earth or MultiMon Taskbar or GoToMyPC close it before starting Pipe2000.
Make sure you have the most current version of the Pipe2000 GUI. For Print Options select PDF or BMP instead of Printer. When the file is displayed there will be an option to print it. Do not use a PDF printer driver, use the PDF option built into Pipe2000.
A line in a system may become closed due to a pressure regulating valve closing; a flow reversal in a pump; a control switch operating with a specified system change, etc. When this happens, if the portion of the system that is cut off is not supplied in any way, then an analysis may not be conducted on that portion. To avoid this, Pipe2000 will open the closed element and continue with the analysis. One way to resolve this issue is to create a "dummy" reservoir connected to the system with a very small diameter pipe.
The Pipe2000 CD has a folder of Audio/Video tutorials (browse the CD to access them). These provide excellent, user-friendly, classroom-like instruction on basic Pipe2000 GUI functions and on many intermediate and advanced functions and features as well. Once the videos have been viewed and the user has created a small practice model, more detailed questions may be answered with the On-Line Help file. Search the Contents page or the index for the topic in question.
The only file that is needed is the .p2k file.
Always make sure you have the most recent version of the Pipe2000 GUI first. If that does not resolve your problem, please contact Tech Support. Attaching the Pipe2000 data file with which you are having trouble gives Tech Support much more insight into the possible cause (see below).
Run the Wibu-Key license manager by clicking START | PROGRAMS | WIBU-KEY | Server-Monitor. When the Server Monitor starts, click the 2nd speed button from the left (with the magnifying glass) to Browse Network. In the left window pane, click on the name of the server (that has the key plugged in) and a list of active users will appear below it. Click on the user that has terminated abnormally, then click the button marked "Cancel User"
Check that your Units Selection is correct. If you mean to use gpm but have selected mgd you will get very high losses. Also make sure that the roughness values you input match the head loss equation you are using. For example, if you select Darcy Weisbach for head loss and input 140 for roughness (which is for Hazen Williams) you will get very high losses.
A Hydropneumatic Tank element has been added to Pipe2000. This sophisticated element includes a pump and control switch so the user only needs to input the low and high pressure operating points and the volume of water supplied between these settings.
