WebFeb 20, 2024 · Flow is proportional to pressure difference and inversely proportional to resistance: Q = P2 − P1 R. For laminar flow in a tube, Poiseuille’s law for resistance states that R = 8ηl πr4. Poiseuille’s law for flow in a tube is Q = (P2 − P1)πr4 8ηl. The pressure drop caused by flow and resistance is given by P2 − P1 = RQ. WebFeb 27, 2024 · In the limit of an infinitely long pipe, it takes an infinite amount of work to push fluid through it, and with a constant pressure pump the flow rate approaches zero. In the case of a positive displacement pump, increasing the pipe length causes the fluid pressure at the pump end of the pipe to go up at a constant flow rate, until the pressure ...
