WebFirst, select the desired pressure loss Δ p / L, say 1 kg / m 2 / s 2 (0.12 in H 2 O per 100 ft) on the vertical axis (ordinate). Next scan horizontally to the needed flow volume Q, say 1 m 3 / s (2000 cfm): the choice of duct with diameter D = 0.5 m (20 in.) will result in a pressure loss rate Δ p / L less than the target value. WebFormula 1 hf = f ( L / D ) ( v2 / ( 2 g ) ) where: f = friction factor (unitless) L = length of pipe (ft) D = diameter of pipe (ft) v = fluid velocity (ft/sec) g = gravitational acceleration (ft/sec 2) Related: Head Loss Darcy - Weisback Equation Head Loss Darcy Calculator - Weisback Equation Babcock Steam Flow Rate Formula and Calculator
