| Abstract: | Starting from the characteristic analysis of water hammer differential equation of pipeline, Rimman invariable and grid analytic solutions are put forward. Analytic solutions of pipeline water hammer are established. The calculative expression of maximum water hammer pressure in long pipelines is given. The analytic solution and numerical results have been compared through practical examples. The gravity component in water hammer differential equation has also been discussed. |
