WebApr 4, 2016 · One of the accepted methods to calculate friction losses resulting from fluid motion in pipes is by using the Darcy– Weisbach equation. For a circular pipe: Where: hf = head loss (m) f = friction factor L = length of pipe work (m) d = inner diameter of pipe work (m) v = velocity of fluid (m/s) g = acceleration due to gravity (m/s2) In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach. Currently, there is … See more In a cylindrical pipe of uniform diameter D, flowing full, the pressure loss due to viscous effects Δp is proportional to length L and can be characterized by the Darcy–Weisbach equation: See more The mean wall shear stress τ in a pipe or open channel is expressed in terms of the Darcy–Weisbach friction factor as See more Historically this equation arose as a variant on the Prony equation; this variant was developed by Henry Darcy of France, and further refined … See more In a hydraulic engineering application, it is typical for the volumetric flow Q within a pipe (that is, its productivity) and the head loss per unit length … See more The friction factor fD is not a constant: it depends on such things as the characteristics of the pipe (diameter D and roughness height ε), the characteristics of the fluid (its … See more Away from the ends of the pipe, the characteristics of the flow are independent of the position along the pipe.
