# Volumetric Flow Rate

Volumetric flow rate, abbreviated as Q, also called flow rate, is the amount of fluid that flows in a given time past a specific point.

## Volumetric Flow Rate formulas

\(\large{ Q = A_c \; v }\) | |

\(\large{ Q = \frac {V} {t} }\) | |

\(\large{ Q = k \; i \; A_c }\) | |

\(\large{ Q = \frac{\pi}{4} \; d \; \bar {v} }\) |

### Where:

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

\(\large{ A_c }\) = area cross-section

\(\large{ \bar {v} }\) = average velocity

\(\large{ k }\) = hydraulic conductivity

\(\large{ i }\) = hydraulic gradient

\(\large{ d }\) = inside diameter of pipe

\(\large{ \pi }\) = Pi

\(\large{ t }\) = time

\(\large{ v }\) = velocity of flow

\(\large{ V }\) = volume of area
