View source: R/hydrailic_functions.R
Description
The phenomenological Colebrook–White equation
(or Colebrook equation) expresses the Darcy friction factor f as a function
of Reynolds number Re and pipe relative roughness ε/Dh, fitting the data
of experimental studies of turbulent flow in smooth and rough pipes.
The equation can be used to (iteratively) solve for the Darcy–Weisbach
friction factor f.
