Shake them the wrong way and they could have a "head crash," a total wipeout that you don't want.
要是以错误的方式摇晃它们,他们很可能会“迎头相撞”,那将是一个你不愿见到的全面崩盘。

At normal delivery and above, when velocity distributions are fairly steady, the pressure and totalhead generated may be derived from the velocity distributions with reasonable accuracy.
在正常流量以上,当速度分布相当稳定时,压力和总扬程可由速度分布推得,并具有较高精度。

The head loss of flume is less, and the average loss is nearly 12% of the totalhead in upstream.
