Darcy Friction Factor
WebThe Fanning friction factor f is used in heat transfer literature because of its ability to represent the momentum transfer process of fluid flow in a manner consistent with the … The Darcy friction factor, fD, is a component of the Darcy-Weisbach equation, used to describe head loss due to friction. Calculating the Darcy friction factor involves the Reynolds number of the flow, the relative roughness of the pipe wall, and the cross-section of the pipe. The Fanning friction factor, f, is … See more For turbulent flow, the Darcy friction factor is calculated using the Colebrook-White equation, which is as follows: where Re is the Reynolds number, ε is the average height of surface … See more The Fanning friction factoris used to calculate the head loss via the following equation: where Δp is the change in pressure, L is the pipe length, and Dis the pipe diameter. … See more Knowing which friction factor to use is important for proper calculation of head loss. Oftentimes, engineers will make use of a chart or table to evaluate a friction factor. These tools usually include a note about which friction … See more max industries wi
