RE: Velocity In Manning Equation
Tom Walski
The St. Venant equations are for non-uniform, unsteady water flow in conduits and channels, not pressure pipes. SewerGEMS and CivilStorm can solve these equations. They also can handle full pipe flow. If you are dealing with steady, non-uniform flow…

RE: Modeling throttle valve
Jesse Dringoli
Hi Mohamad, The numerical solver in WaterCAD and WaterGEMS (steady state and EPS) is demand-driven so if you enter a fixed demand at a junction, it will solve the rest of the network under the assumption that the specific demand must be supplied. So…

RE: calculate flow
Jesse Dringoli
Mohamad, Is this for academic purposes or for a real system? Consider the three approaches to solve the system: 1) Demand-driven: If you enter demands at junctions, the pipe flow is essentially fixed as the model solves around that. 2) Boundary…

RE: Velocity calculation
Joeri Legierse
The pipes seem to be layed out in series (not parallel), since WaterGEMS is demand driven the demand at (or behind) junction J-1 will determine the flow in both pipes.This flow is equal for both pipes (assuming no demand on junction J6) since there is…
