Process Equipment and Plant Design Pressure drop due to pipe fittings can be estimated by the equation, ΔP/p = 4f.Le/D.V2/2gc, where, Le = equivalent length of straight pipeline which will incur the same frictional loss as the fitting and D = diameter of the fitting. The value of Le/D (dimensionless) for 45° elbow and 180° close return bends would be respectively around 45 and 75 300 and 500 5 and 10 180 and 300 45 and 75 300 and 500 5 and 10 180 and 300 ANSWER DOWNLOAD EXAMIANS APP
