Darcy-Weisbach Formula - Pipe Flow

The Darcy-Weisbach equation Weisbach 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:

Darcy Friction Factor Formulae in Turbulent Pipe Flow

ow is calulated using the Darcy-Weisbach equa-tion. This equation includes the Darcy friction factor. The exact solution of the Darcy friction factor in turbulent ow is got by looking at the Moody diagram [5] or by solving it from the Colebrook equation [1]. If the Darcy friction factor must be known only once, the Moody diagram is good.
