| Abstract: | Two equations for calculating friction loss and the difference methods for their solution in hydraulic transient calculation are discussed in this paper. The comparison of calculating results is given. It is found that a smaller calculated friction loss leads to a quicker attenuation of surge pressure. Using Darcy-equation to calculate friction loss is more convenient, but using the comprehensive equation can improve calculation precision. A empirical method of dealing with pump station boundary condition of a long-distance pipeline is given. |
