Problem:
How to model pressure drop in a piping system?
Solution:
As of Feb 2024, AutoPIPE does not perform any kind of pressure drop / flow rate calculations along the pipe. In the past there was another application called PlantFLOW that was developed By Bentley to simplify the process of piping network flow analysis. PlantFLOW calculated pressure drops and flow velocities in both open and closed networks to assist engineers in pipe sizing, meter station design, and compressor, pump, and heat exchanger pressure loss evaluations. However this application has been deprecated. If you would like to see these features added into AutoPIPE, please search for / log a new IDEA using instructions here.
The more votes we have for a feature the quicker the feature will be added into the program.
Model Pressure Drop,
Assuming an external source provides pressure drop profile for the piping system, suggest adding close space node points and varying the pressure setting between each set of connected node points as needed.
Example, Pipe arrangement with 5 elbows along the path.
1. With Given piping arrangement
2. Go back to the first node point, use insert Run command to add more node points between Start and First elbow.
3. Repeat steps above for remaining pipe runs between elbows and end of pipe.
4. Go to the Press/Temp/Pipe ID tab in the input grids, change Pressure values along the pipe run as needed.
Note, all values used in this example are fictitious. Please use values needed for your project.
Model Flow Rate
Once more, AutoPIPE does not calculate a flow rate. The only Flow Rate in the program is associated with the Fluid Transient. For details of this approach please see AutoPIPE help for Water Hammer (Time History) Example. Again, if this is not enough please search for an existing IDEA or add a new one as mentioned above.
