(7.1)

where

Q - Pump flow rate, gal/min

H - Pump head, ft

E - Pump efficiency as a decimal value, less than 1.0

Sg - Liquid specific gravity (for water Sg = 1.0)

In SI units, power in kW can be calculated as follows:

(7.2)

where

Q - Pump flow rate, m3/hr

H - Pump head, m

E - Pump efficiency as a decimal value, less than 1.0

Sg - Liquid specific gravity (for water Sg = 1.0)

For example, if the BEP on a particular pump curve occurs at a flow rate of 3 000 gal/min, 2 500 ft head at 85% efficiency, the BHP at this flow rate for water is calculated from Equation (7.1) as
