Online Pump Power calculator.
Pump Power Formulas:
Imperial Units:
P = (Q * H * SG) / (3960 * η)
where:
P = power, horse power.
H = head, ft.
Q = flow, gpm.
SG = specific gravity.
η= pump efficiency, decimal.
SI Units:
P = (Q * H * SG) / (367 * η)
where:
P = power, kW.
H = head, m.
Q = flow, m3/hr.
SG = specific gravity.
η= pump efficiency, decimal.
