From this, we can conclude that the discharge coefficients of the inletopening and the outlet opening are different.
由此可推出进、出口的流量系数不同，从而得到一种简单的估算自然通风量的计算方法。

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 inletopening was studied;
The invention relates to a metering element (10) for flowable and bulk materials, in a deformable, in particular elastic basic body, having a round inletopening (11) and a slot-shaped outlet (21).
