WebII. The Friction Factor This brings us to the most interesting and complex part of the equation, the friction factor. The first complication that arises is that there are two common friction factor definitions in standard usage : the Fanning and the Darcy-Weisbach.. In the nineteenth century, two groups approached the fluid flow WebWhite have contributed to the development of formulae for calculation of friction factors and head loss due to friction. The Darcy Friction factor (which is 4 times greater than the Fanning Friction factor) used with Weisbach equation has now become the standard head loss equation for calculating head loss in pipes where the flow is turbulent.
