Diagonal square pitch Square pitch Heat transfer rate is independent of tube arrangement Triangular pitch Diagonal square pitch Square pitch Heat transfer rate is independent of tube arrangement Triangular pitch ANSWER DOWNLOAD EXAMIANS APP
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 300 and 500 5 and 10 180 and 300 45 and 75 300 and 500 5 and 10 180 and 300 45 and 75 ANSWER DOWNLOAD EXAMIANS APP
