Friction factor for turbulent flow formula
WebThe friction factor for laminar flow is independent of the roughness of the pipe’s inner surface. f = 64/Re. The friction factor for turbulent flow depends strongly on the relative roughness. The Colebrook equation determines it. It must be noted that the friction factor is independent of the Reynolds number at very large Reynolds numbers. WebJan 8, 2024 · Equation () is implicit in f; to solve this equation, it is necessary to implement a numerical scheme.Nowadays that is simple to do due to the advent of computing; but at the time this model was proposed, …
