# Volumetric Flow Rate

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Volumetric flow rate ( $$Q$$ or $$V$$ ) (also called flow rate) is the amount of fluid that flows in a given time past a specific point.

### Volumetric Flow Rate formula

$$\large{ Q = A v }$$

$$\large{ Q = \frac {V} {t} }$$

$$\large{ Q = k i A }$$

Where:

$$\large{ Q }$$ = volumetric flow rate

$$\large{ A }$$ = cross section area

$$\large{ i }$$ = hydraulic gradient

$$\large{ k }$$ = hydraulic conductivity

$$\large{ t }$$ = time

$$\large{ v }$$ = flow velocity

$$\large{ V }$$ = area volume
