The engineering parameters of a pump-station water supply system located in China are shown in Table 1, and the schematic diagram of the pipeline system is shown in Figure 3. The pipeline rises uniformly in profile. According to some particular engineering principles in China, the limited rate of pressure rise in the pipeline system *φ*_{2} = 30%. The polytropic exponent *m* = 1.2. Since this water supply project is still under construction currently, no measured data about the pipeline system could be presented for now. Therefore, the simulation numerical computation, which is on the basis of the method of characteristics (Streeter & Wylie 1963; Wylie *et al.* 1993; Chaudhry 2014), was given instead of measured data to make a comparison with the theoretical result.
