Solved Examples for Friction Loss Formula Q.1: Find out the friction loss, if the inner diameter and length of the pipe are 0.3 m and 30 m respectively. Also, the friction factor and velocity of the liquid are 0.4 and 25 m per sec? Solution: Given parameters, Length of the pipe, L ...
Colebrook Friction Loss Formula for Round Ducts In the region of laminar flow (Reynolds numbers less than 2300),the friction factor is a function of Reynolds number only. For completely turbulent flow (fully rough), the friction factor depends on duct surface roughness and internal protuberances (...

In summary, the formula for minor loss due to contraction can be expressed as k[(mean velocity)^2]/2g, while the formula for minor loss due to expansion is also k[(mean velocity)^2]/2g, with the mean velocity being the velocity averaged over the cross section of the pipe. The old ...
