Pressure drop in pipe fittings and valves equivalent

If the overall pressure drop is equivalent to a pipe length of 16 diameters,and the pressure drop due to the actual flow path length (which is affected by the roughness) is equivalent to only 2.5 diameters then it can be seen that a small change in the wall friction inside the bend will have a very small effect on the total pressure drop.Pressure Loss from Fittings - Equivalent Length Method Fittings such as elbows,tees and valves represent a significant component of the pressure loss in most pipe systems.This article details the calculation of pressure losses through pipe fittings and some minor equipment using the equivalent length method.The strength of the equivalent length method is that it is very simple to calculate.The weakness of the equivalent length method is that Pipe Sizing - Roughness figures and equivalent range 17 rows Pipe Sizing Roughness figures and equivalent range #0183;Range Roughness Range Roughness Range Roughness Steel BS 1387 Medium 0.046 Steel BS 1387 Heavy 0.046 Galvanised BS 1387 0.15 Copper BS 2871 Table X
