In this article discussed about pump basic formulas with examples like pump power calculation formula, specific speed of centrifugal pump and affinity laws for centrifugal and displacement pumps. Also provided online calculator for pump power calculation.

Pump Power calculator: Enter the flow, fluid density (available at the bottom), gravity, head and pump efficiency. Then press the calculate button to get the pump power, motor power. Also, you can change the power unit from kW to HP.

P = power depend on: kW, H = head, m, Q = flow, m3/hr, SG = specific gravity, η= pump efficiency, decimal.

The hydraulic pump power calculation is done thanks to the pump flowrate, the pump head and the density of the fluid being pump. Pump power formula is the following : P hydraulic = Q.H.ρ/367. In case the density is changing significantly when the fluid goes through the pump, the density at the inlet is used. Equation 1 : Pump Hydraulic Power ...
