Manifold force main modeling
Manifold force main modeling
(OP)
I have about 11 pump stations using the mainfold force main. I was asked to do an hydraulic analysis to evaluate the two at end of the force main (farthest) by watercad.
How should I do? I mean there are 9 other pump stations, which one(s) should I put on, which one should I put off?
Is there any rule to set up the stutus of the pumps (on/off) to evaluate the other pump (the one I want to valute)?
Thanks,

It is difficult to decide which pump(s) should be on or off. In my idea, I checked the pump run time, if the run time is very short, like 2~6hr/day, I would set it off. Is this approach reasonable?
Thank you for your response.

Always check your results! I have got screwy results on occasion when puting multiple pumps in the same manifold from water CAD. Just make sure the pumps will operate at the point Water CAD says they are going to and the friction losses in each section of pipe match the flows that are listed.
