Dear Bentley Team,
We need to calculate max flow going from tie in point (pressure is 6 barg ) to two tankers (pressure is atmospheric), & to control the pressure, we have provided control valve PRV with a flow coefficient of 702 l/s bar, as per calculation we are getting 1624 m3/hr, even thou we set the initial pressure value at different pressures it is showing same flow, i have attached file for your review please.
And also we need to maintain some pressure like 1 bar or 2 bar downstream side of the PRV, where to provide this PRV set point on the model, that means PRV will give constant downstream pressure irrespective of upstream flow & pressure fluctuation.
If we get any information how to model the PRV, FCV, PSV, TCV in waterGEMS then it will be helpful.
It all depends on what you are physically doing to control the flow. Are yo using a globe or gate valve (TCV), do you have a control loop to automatically control flow (FCV), or what. You would not use a PRV in this case because a PRV control downstream pressure and that doesn't sound like what you need.
Hello Jayakanthan,
To add to Tom's response, you can find information on FCVs here, and on using TCVs in WaterGEMS and WaterCAD here.
Regards,
Scott
