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.

WebThus dynamic viscosity can be expressed as the tangential force per unit area required to move the fluid in one horizontal plane with respect to another plane, with a velocity of unit value while the fluid’s molecules maintain a unit distance apart.
