# Power

Power, abbreviated as P or PWR, is the rate of doing work or the rate of using energy per unit time**.**

## Formulas that use Power

\(\large{ P = \frac{W}{t} }\) | |

\(\large{ P = F \; v }\) | |

\(\large{ P = \frac{F \; d}{t} }\) | |

\(\large{ P = \Delta p \; Q }\) | |

\(\large{ P = \gamma \; h_l \; Q }\) |

### Where:

\(\large{ P }\) = power

\(\large{ d }\) = displacement

\(\large{ F }\) = force

\(\large{ h_l }\) = head loss

\(\large{ \Delta p }\) = pressure drop

\(\large{ \gamma }\) (Greek symbol gamma) = specific weight

\(\large{ t }\) = time

\(\large{ v }\) = velocity

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

\(\large{ W }\) = work
