Define fanning friction factor

WebThe friction factor f appearing in Eqs. (4.5-6) and (4.5-7) is also called the Fanning friction factor. However, this is not the only definition for f available in the literature. Another commonly used definition for f is the Darcy friction factor, fD, which is four times larger than the Fanning friction factor, i.e., fD = 4 f.
