"WebUsing this equation, pressure drop ‘∆p’ in the laminar regime across ‘l’ length of the pipe can be easily calculated. To summarize the laminar flow equation: The flow rate is directly proportional to the radius of the pipe. Thus, the small increase in pipe diameter can significantly increase the flow rate in the system. " - Flow equations

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. WebIn laminar flow, 16 Re f = . In turbulent flow we can use either the Colebrook or the Zigrang-Sylvester Equation, depending on the problem. Both give equivalent results within experimental uncertainty. In these well equations, ε is the average roughness of the interior surface of the pipe. A table of roughness
