Pump Hydraulic Power

Total dynamic head, hydraulic horsepower, brake horsepower, and motor power from flow, pressures, elevations, and efficiencies. Applies separate design margins to flow and head per typical sizing practice.

Method: HHP = Q × TDH × SG ÷ 3960; BHP = HHP ÷ ηpump; Motor HP = BHP ÷ ηmotor. Reference: Hydraulic Institute Standards; Karassik, Pump Handbook; ANSI/HI 1.3 centrifugal pump sizing.
