Water-hammer computations for small hydro

When the preliminary layout and hydraulic parameters of the hydropower facility are selected, an analysis for water-hammer and other pressure surges caused by various possible operating conditions must often be conducted. A significant amount of time may be spent writing a computer program to suit the actual situation. A menu-driven microcomputer program, SURGE, for waterhammer analysis of various hydroplant arrangements, has been developed. The program is suitable for small hydropower in that it is designed to handle various hydroplant arrangements without altering the code. Thus, the water-hammer computations for a proposed facility may be accomplished quickly and at a low cost. The program is described in this paper. (from Authors)
