WebApr 13, 2015 · The Darcy friction factor varies widely with pipe roughness. As the pipe wall roughness increases, the head loss increases. Pipe Size Pipe is available in different sizes and schedules or wall thicknesses. Users often mistakenly use the pipe’s nominal size instead of the actual ID when performing the head loss calculations. WebWeisbach first proposed the equation we now know as the Darcy-Weisbach formula or Darcy-Weisbach equation: hf = f (L/D) x (v2/2g) 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) or: hf = head loss (ft) f = friction ...

Web1. Henri P.G. Darcy (1805–1858) was a French civil engineer. He gave his name to the Darcy–Weisbach friction factor. 2. The hydraulic diameter and hydraulic radius are defined respectively as: where the subscript H refers to the hydraulic diameter or radius, A is the cross-sectional area and Pw is the wetted perimeter.
