The article presents the theoretical studies results of hydraulic shock with flow continuity rupture in the pressure the pumping station pipeline. Calculated dependencies are obtained for calculating the shock pressure magnitude and the first period duration of reduced pressure, taking into account the hydraulic resistance along the pipeline length in the discontinuity event in the flow. The calculation results are compared with the Professor D.N. Smirnov’s experiments results.Comparative calculations using the proposed method with D.N. Smirnov experimental data gives a satisfactory agreement and confirms the proposed method reliability.
