Please see below for guidance on the factors within the head loss calculation. Equivalent pipe length
WebThe ratio L/D is equivalent length in pipe diameters of straight pipe that will cause the same pressure drop or head loss as the valves or fittings under the same flow conditions. As the resistance coefficient is K is constant the equivalent length L/D will vary inversely with the change in friction factor for different flow conditions. WebThe advantage of the equivalent length method is that it is very simple to calculate. All pipe runs and fittings can be summed up to make one total length, and the pressure loss calculated from this length. There are …
