water hammer analysis
(OP)
Dear all,
i'm new engineer and need your help to make water hammer analysis i was reading a different document that discribe water hammer and devices to prevent or minimize her effect but i didn't find an easy procedure to do it.
please see attachad file :
it's the shematic of the system that i need to study.
how to select the best device ? and can surge anticipating valve replace Surge tank.
thank you in advance for your kind help.

RE: water hammer analysis
In any case, to model this accurately including the pump and F control valve you're going to need a computer program to do it right. Any surge pressure will depend on how fast the pump spins up or stops and how fast the FCV reacts to to the pump's action. You might also consider that the FCV fails and slams shut.
I think your 80/50 reducer is shown backwards.

Biginch please could you tell me what software to use to make the analysis.
and how to estimate time of respone of pump in case of quick power failure.
Best regards.

Here is an article that you can use to evaluate your system:

The worst case analysis to consider will be power failure, with the pump stopping immediately.
