Pipe friction factor chart
Webb8 jan. 2024 · The friction factor is traditionally computed through Colebrook’s equation or by using Moody’s chart. However, these approaches have shown their limitations in getting accurate values for such factor. Different models to calculate the friction factor have been proposed, achieving different levels of certainty. In this paper, we revisit the distinct … WebbD p = pressure loss in Pa. L = friction factor (a number without dimension) p = density of water in kg/m3. V = flow rate in m/s. D = pipe diameter in m. L = pipe length in m. The expression above shows that calculations of pressure losses rest entirely on the determination of the coefficient L. Flow type.
