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. … 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 $${\displaystyle \tau ={\frac {1}{8}}f_{\text{D}}\rho {\langle v\rangle }^{2}.}$$ The wall shear … See more Away from the ends of the pipe, the characteristics of the flow are independent of the position along the pipe. The key quantities are then the pressure drop along the pipe per … See more The Darcy-Weisbach's accuracy and universal applicability makes it the ideal formula for flow in pipes. The advantages of the equation are as follows: • It is based on fundamentals. • It is dimensionally consistent. 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 … 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 into the form used today by 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 S (the concomitant power consumption) to be the critical important factors.
