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 [m3/s] in basic SI units or ft3/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 [m3/(m2s) ]. The integration of a flux over an area gives the volumetric flow rate. Volumetric flow rate is also linked to viscosity.
