WebMar 5, 2024 · The pressure difference (P out-P in) between two points in the pipe is due to the frictional resistance, and the head loss h L is directly proportional to the pressure difference. The head loss due to friction can be calculated from the Darcy-Weisbach equation: where:: head loss due to flow resistance. f: Darcy-Weisbach coefficient. L: … WebThe friction loss for each bend is: Δ p f f = ζ x 1 2 ρ w x 2 = 673.2 P a. The total friction loss for the 10 bends is. Δ p f f = 10 ⋅ 673.2 P a = 6732 P a = 0.067 B a r. Step 6 Calculate the entire friction loss for the pipe including the fittings in this case only 90° bends but normally it also includes valves, reducers, equipment etc.
