The Darcy friction factoris a dimensionless quantity used in theDarcy–Weisbach equation, for the description of frictional losses in pipe or duct as well as for open-channel flow. This is also called theDarcy–Weisbach friction factor,resistance coefficient, or simplyfriction factor. The friction ...
Goudar equation is the most accurate approximation to solve directly for the friction factor for a full-flowing circular pipe. It is an approximation of the implicit Colebrook–White equation. Equation has the following formDarcy friction factor formulaeAshrae Handbook of Fundamentals...

The Darcy-Weisbach equation Weisbach first proposed the equation we now know as the Darcy-Weisbach formula or Darcy-Weisbach equation:h f = f (L/D) x (v2/2g)where:h f = head loss (m)f = friction factor L = length of pipe work (m)d = inner diameter of pip e work (m)v = ...
13.5.2.2 Friction Factor Equation The Darcy-Weisbach equation is one of the most general friction head loss equations for a pipe segment. It is expressed as: (13-22)hf=fLDV22g (13-23)f=f(Re,ɛ/D) where f is the friction factor, Re = VDρ/μ is the Reynolds number, and ɛ/...
