12.4: Viscosity and Laminar Flow; Poiseuille’s Law

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.
