| Abstract: | With the application of the theory of water hammer and the characteristics method, this paper sets up the mathematical models to simulate the boundary conditions of surg tanks and parellel pumps with several pipelines during water hammer process, analyzes the protective properties of surge tanks for water hammer due to power failure in different combinations of operation, studies the effect of valve closing procedure on the pressure in pipelines and the water level variations in surge tanks, puts forward a method to determine the economical sections of surge tanks, and obtains conclusions which is of practice for the optimum design of projects. |
