# Volumetric Flow Rate

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

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 or you could say the actual volume flow.

## Volumetric flow rate formula

$$\large{ Q = A_c \; v }$$
Symbol English Metric
$$\large{ Q }$$ = volumetric flow rate $$\large{\frac{ft^3}{sec}}$$ $$\large{\frac{m^3}{s}}$$
$$\large{ A_c }$$ = area cross-section $$\large{ft^2}$$ $$\large{m^2}$$
$$\large{ v }$$ = velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
