WebNov 30, 2024 · The equivalent length method (The Le/D method) allows the user to describe the pressure loss through an elbow or a fitting as a length of straight pipe. This method is based on the observation that the major losses are also proportional to the velocity head (v2/2g). How much length do pipe fittings add? Webequivalent length of pipe 2 in terms of diam1 = Actual length of pipe 2 x (diam1 / diam2)^5. The following example illustrates this method. A pipe roughness of 0.05 mm is assumed (i.e. commercial steel). The flow direction is from the 100 mm section, through the reducer, and then through the 80 mm section.
