All fluids are compressible to an extent; that is, changes in pressure or temperature cause changes in density. However, in many situations the changes in pressure and temperature are sufficiently small that the changes in density are negligible. In this case the flow can be modelled as an incompressible flow. Otherwise the more general compressible flow equations … WebFlow velocity.

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.
