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。
the invention relates to a metering element (10) for flowable and bulk materials, in a deformable, in particular elastic basic body, having a round inlet opening (11) and a slot-shaped outlet (21).
during experiment, a directly connected wind tunnel was independently designed to simulate a free stream mach at 5.3, based on which the dynamic process of inlet opening was studied;
