piping system curve
(OP)
we have a closed loop cooling water system with an expansion tank before the pump feeding the chiller. should this be included when making a system curve?

RE: piping system curve
If the return enters below the liquid level, yes and no. There is no lift needed, but you need to include the entrance loss into the suction piping, which is at the tank, and the exit loss from the discharge piping, which is also at the tank.
Use Bernoulli's theorem and you'll see what I'm talking about.
Good luck,

If the return to the tank enters above the liquid level then a hydraulic lift is required that is dependent on the size and shape of the tank. This may or may not add significantly more head to the system curve, it depends on the tank.
Good luck,

If there is a static lift, it must be allowed for as Latexman states (equivalent to serving a cooling tower, for example).
