WebFeb 27, 2011 · They always pointed out the relationship to the Fanning friction factor, and in the more recent editions the Moody friction factor as well. C&R's friction factor, which I have called the Stanton friction factor in my Uconeer units conversion program, is 1/2 of the Fanning factor and 1/8 of the Moody factor. http://info.mheducation.com/rs/128-SJW-347/images/Pipe-Flow-Friction-Factor-Calculations-with-Excel-Spreadsheets-3-June-15-final.pdf

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. The subscripts are being used in this book to avoid confusion between the two different ... healthy diabetic diet plan
