Webequation has been written by Brown [5]. Two variants of the friction factor are in common use: the Darcy friction factor f. D, which Moody plotted, and the Fanning friction factor f. F, which equals one quarter of the Darcy factor, as expressed in Equation 3. Versions of the diagram for both friction factors have been prepared. h. f = f. D. L D ... WebThe relationship between the Fanning friction factor and the Moody friction factor is: fm = 4 ff. Note that the m and f subscripts are not typically used. The symbol f is commonly used for both the Moody friction factor and the Fanning friction factor.
