The calculation is valid for smooth pipes.
The nominal length of the pipework is calculated by adding the straight pipe runs and the equivalent length of each joint or fitting.
The equivalent lengths of the joints and fittings can be calculated from the list or simply estimated as 60% of the straight runs, i.e. total length = total straight runs x 1.6.
