WebhL is the frictional head loss due to fluid flowing at an average velocity, V, through a pipe of length, L, and diameter, D, with Moody friction factor equal to fm. The frictional head loss will be in ft for U.S. units and in m for S.I. units. g is the acceleration due to gravity. (g = 32.17 ft/sec2 = 9.81 m/s2) WebPipe Fitting Losses. Pressure loss in a pipe due to fittings such as elbows, tees, valves, expanders and reducers based on 3K and 2K method. Pipe. Pipe Size (inch) Schedule / Thickness. Pipe Roughness, ε. inch.
