• This paper describes a method of analysis of waterhammer in a pump system including pipelines, bifurcations, surge tanks, reservoirs and pumping stations, where pumps installed in series are operated in parallel. Hydraulic losses are included in the analysis. The analysis is carried out by solving the fundamental equations under boundary conditions by a digital computer. The computer program is composed of several subprograms, by which hydraulic transients in each element of the pump system are computed. Two examples are calculated. One is the waterhammer at a pump installation, where three pumps are operated in parallel and five one-way surge tanks are installed along a discharge line. Computed results are compared with measurements. Another example deals with a pump system, where four main and booster pump sets installed in series are operated in parallel. The water-hammer after power failure in some of pump sets is calculated.
