This friction factor is one-fourth of the Darcy friction factor, so attention must be paid to note which one of these is meant in the "friction factor" chart or equation consulted. Of the two, the Fanning friction factor is the more commonly used by chemical engineers and those following the British convention. The formulas below may be used to obtain the Fanning friction factor for common applications. http://achp.readthedocs.io/en/latest/ACHPComponents/FluidCorrelations.html

Colebrook equation suffers from being implicit in unknown friction factor and thus requires an iterative solution where convergence to 0.01% typically requires less than 7 iterations. Implicit Colebrook equation cannot be rearranged to derive friction factor directly in one step. blackwood nursery class

WebJan 1, 2012 · The Andresen–Garimella correlation uses the Churchill single-phase friction factor model, which would provide the opportunity to consider roughness. However, the Andresen–Garimella correlation was developed assuming smooth tubes and using the coefficient a during the curve fitting.
