Bushels per second (U.S.), Volumetric flow rate
In fluid dynamics, the volumetric flow rate, also volume flow rate and rate of fluid flow, is the volume of fluid which passes through a given volume per unit time (for example cubic meters per second [m
3/s] in basic SI units or ft
3/s). It is usually represented by the symbol Q. Volumetric flow rate should not be confused with volumetric flux, represented by the symbol q with units of [m
3/(m
2s) ]. The integration of a flux over an area gives the volumetric flow rate. Volumetric flow rate is also linked to viscosity.
