WebFriction Factor. The friction factor is a measure of the resistance to flow by a pipe. It was developed in the 1930s and remains the basis for computing pressure drop due to friction [18]. There are two “flavors” of friction factor; the Darcy (or Moody) friction factor is equal to four times the 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.
