WebhL = K (V²/2g) where, K is resistance coefficient due to fittings, V is fluid velocity and g is acceleration due to gravity. Friction losses hF is calculated as. hF = f (L/D) (V²/2g) where, … WebMay 4, 2015 · The resistance coefficient K can be thought of as the number of velocity head loss caused by a valve or fitting. The value of K is constant when the flow is in the zone of complete turbulence. The value of K can be calculated from the geometry of the valve or fitting based on empirical results obtained from a variety of test data. WebPressure losses due to valves, fittings, expansions, and contractions can be calculated using flow resistance coefficients that specify the number of velocity heads corresponding to the loss in each element of a pipeline. Methods for estimating these coefficients for two-phase flow can be found in Refs. [2, 8, 24, 26 ]. how many games in mlb division championship
