PUMP HEAD CALCULATION FROM TONS(TR) OR GPM & ITS THUMB RULE
How should we calculate Pump Head through any thumb rule for a given GPM or Tons for a Chiller Pump?
The process I came across is a long process of calculating Head loss at every pipe run. But I wanna know any thumb rule so that during tendering/estimation of any project, I can analyse the Pump capacity required for the project.
Is there any relation between the GPM and Pump Head from which it can be directly evaluated?
Awaiting kind help please.
pump curves are available from most pump manufactures.
Impeller design will dictate what you seek.
but in all cases, to increase flow one must decrease pressure.
