The research can effectively optimize the aqueduct hydraulic loss calculation and make design parameters more accuracy. By analysis of four commonly used hydraulic loss calculation formula, to study how to select the correct formula, optimize the calculation process for the different pipes and consider water loss and local water loss along the process of calculations. It found the different formulas used in the calculation of the different pipes, and provides a calculation error caused due to water hammer and other reasons. The conclusions is that considering the factors affectin~ the hydraulic loss for the hydraulic calculation is necessary.
