Calculation of pressure drop

• The nominal length of the pipeline is calculated by adding together the length of the straight pipeline and the equivalent lengths of the fittings installed.
• An estimate of the equivalent lengths of the fittings can be provided using the adjacent program or accepted on an approximate basis by adding 60% onto the length of the straight pipeline, e.g. nominal length = length of straight pipeline x 1.6.
• The calculation is valid for smooth pipes.
