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. WebLaminar Flow. Laminar flow is the movement of fluid particles along well-defined paths or streamlines, where all the streamlines are straight and parallel. Hence, the particles … WebTurbulent flow is a type of flow in which the fluid particles move in a zig-zag manner. The movement in zig-zag manner results in high turbulence and eddies are formed. This results in high energy loss. The flow is turbulent when the Reynolds number is greater than 4000. A fluid flow in a pipe, that has a Reynolds number between 2000 and 4000 ... shwetark plant
