| Abstract: | In the paper, the method of pressure loss and liquid temperature rising calculation in the steady one-state flow is analyzed. Then the method of flux and vapor rate in the steady two-state flow is introduced. At last, the most familiar unsteady process, the cooling of pipe, the filling of close branding pipe, the opening of valve, is analyzed and how to calculate the max of pressure fluctuation in the three process is generalized. |
