Pumping Systems and Performance

The specific speed of a given type pump must not exceed the specific speed values presented by the Hydraulic Institute [17]. This is based on a known or

The values of friction loss (including entrance, exit losses, pressure drop through heat exchangers, control valves and the like) are hSL and hDL. The total static head is D -SL, or [(D + D ) — (—SL)] if siphon action is ignored, and [(D + D ) — (S L)] for worst case, good design practice. 

Calculate the friction losses hSL and hDL for three or more arbitrarily chosen flow rates, but rates which span the area of interest of the system.
