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. WebThe imperial form of the Hazen-Williams formula is: hf = 0.002083 x L x (100/C)^1.85 x (gpm^1.85 / d^4.8655) where: hf = head loss in feet of water. L = length of pipe in feet. C = friction coefficient. gpm = gallons per minute (USA gallons not imperial gallons) d = inside diameter of the pipe in inches. The empirical nature of the friction ...
