WebFlow Rate Formula. The flow rate of a liquid is a measure of the volume of liquid that moves in a certain amount of time. The flow rate depends on the area of the pipe or channel that the liquid is moving through, and the velocity of the liquid. If the liquid is flowing through a pipe, the area is A = πr2, where r is the radius of the pipe. WebQ = volume flow rate [m 3 /s] P 2 – P 1 = pressure difference between the two ends [Pa or N/m 2] R = resistance to flow [N-s/m 5] Note that this equation only applies to laminar flow— that is, fluid smoothly flowing in layers without mixing.
