Water Horsepower

Water Horsepower formula

\(\large{ WHP = \frac{ Q \; h_t }{3960} }\)
\(\large{ WHP = \eta_p \; BHP  }\)

Where:

\(\large{ WHP }\) = water horsepower

\(\large{ Q }\) = flow rate discharge

\(\large{ \eta_p }\)  (Greek symbol eta) = pump efficiency

\(\large{ h_t }\) = total head
