When calculating the head loss, or pressure change, due to friction, the Fanning friction factor is applied as follows: where Δh is the head … WebThe head loss due to friction is given by the Fanning equation as follows: (6.20) where Hl = frictional head loss (ft. (m)), Fm = Moody friction factor, dimensionless, ff = Fanning friction factor, dimensionless, L = pipe length (ft. (m)), D = pipe diameter (ft. (m)), V = fluid velocity (ft./s (m/s)),
WebThe Moody friction factor - λ (or f) - is used in the Darcy-Weisbach major loss equation. The coefficient can be estimated with the diagram below: If the flow is transient - 2300 < Re < 4000 - the flow varies between … 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.
