Actually, in the tube engineering, the proportion of the loss of local water head in the loss of pipeline water head is big.
在实际管道工程中，阀门阀道的局部水头损失占管路水头损失的比例是相当大的。
Ulteriorly, considering the local head loss in inlet opening and pipes junction plays more important role in the calculative results of water hammer pressure calculation of the short pipeline system.
考虑进口及多管道连接处的局部水头损失对短管道系统水击压强的计算结果影响较大。
There are four emphases in -research, for instance, flow state in pipeline, distribution of concentration and velocity, deposition-limit velocity and calculation of flow resistance or head loss.
研究重点主要集中在管内流动状态、浓度和速度分布、临界流速及阻力损失计算四个方面。
