Witryna20 lut 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. WitrynaGoverning Equations of Fluid Flow and Heat Transfer Following fundamental laws can be used to derive governing differential equations that are solved in ... For Newtonian fluids viscous stresses only depend on the velocity gradient and the dependency is linear. Also it is known that ̿needs to be rebound tachycardia
