Volume flow rate is the amount of liquid (water, gas etc) that passes through an area per unit time.
The volume flow rate formula is: Volume flow rate = flow area * flow velocity
SI volume flow rate is cubic meters per second, US customary unit is cubic feet per second. Other common volume flow units are cubic inches per minute, barrel per hour, gallon per second and liter per second.
