WebFeb 28, 2024 · BACKGROUND The Colebrook-White equation is used to solve for the Darcy Friction Factor (f) for use in the determination of friction losses in pipe and open-channel flows. The equation is expressed in terms of: This module implements various approximations of the function for use in pipe flow calculations. HOW TO USE USE AS … WebDescription In fluid dynamics, the Darcy friction factor formulae are equations that allow the calculation of the Darcy friction factor, a dimensionless quantity used in the Darcy–Weisbach equation, for the description of friction losses in pipe flow as well as open-channel flow.
