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 …

WebFeb 3, 2024 · There are many equations for determining the flow in natural gas pipes and the pressure drops associated with those flows, or vice versa. Our intent is to determine the validity of each equation with respect to … WebJul 21, 2024 · The thrust depends directly on the mass flow rate through the propulsion system. For flow in a tube, the mass flow rate is a constant. For a constant density flow, if we can determine (or set) the velocity at some known area, the equation tells us the value of velocity for any other area. If we desire a certain velocity, we know the area we ... WebFeb 20, 2024 · This equation describes laminar flow through a tube. It is sometimes called Poiseuille’s law for laminar flow, or simply Poiseuille’s law. Example \(\PageIndex{1}\): Using Flow Rate: Plaque Deposits Reduce Blood Flow ...
