The head loss . h f is related to the Fanning friction factor f through 2 f 2 LV hf Dg = or alternatively we can write the pressure drop as . 2 (2) L Pf V D ρ ∆= Friction Factor . In laminar flow, 16 Re f = . In turbulent flow we can use either the Colebrook or the Zigrang-Sylvester Equation, depending on the problem. 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 …
