A calculation comparison on the pipeline network system consisting of pipe sections of short length is made herein with three calculation methods respectively, i. e. neglecting the local energy loss at junctions ; adopting constant local energy loss coefficients and the semi - empirical relationships based on experimental data related to the flow conditions, from which the calculated results for the flow rates of the pipe sections are largely deviated
文中分別應用三種計算方法，即忽略結點處局部能量損失、採用恆定不變的結點局部能量損失系數，以及根據試驗成果所得的與水流條件有關的半經驗公式，針對短管段構成的管網系統進行了計算比較，管段流量的計算結果相差很大。
