# Brake Horsepower

## Brake Horsepower formula

\(\large{ BHP = \frac{100\;Q\;h_t}{3960\;n} }\) |

### Where:

\(\large{ BHP }\) = brake horsepower

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

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

\(\large{ n }\) = total pump efficiency

\(\large{ BHP = \frac{100\;Q\;h_t}{3960\;n} }\) |

\(\large{ BHP }\) = brake horsepower

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

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

\(\large{ n }\) = total pump efficiency
