| Abstract: | The Priessmann method is applied to calculate the hydraulic transient of open channel surge pool pressure conduit system. The basic equations for calculation of flow in pressure conduit by means of characteristic method are deduced and the numerical model for the system is established. Boundary conditions are analyzed. The problems occurred to the calculation are discussed according to the result of a typical open channel surge pool pressure conduit system and the corresponding methods for solution are suggested. |
