| Abstract: | Water transportation and distribution pipe line is the important part of the urban water supply system, and the frictional head loss calculation is the key point of the water transportation and distribution pipe line design. This paper discussed the applicability of the usual head loss calculation formula and its parameters selection. Hydraulic calculation should employ adaptive calculation formula according to different water current and select corresponding hydraulic calculation parameters, so the hydraulic calculation results would be accurate and reliable. |
