A Wirtz Pump is a hollow spiral, mounted vertically. It is arranged such that one end dips below water once per revolution, while the other end (at the center of the spiral) is connected to a vertical tube. When rotated, it can be used to pump water to a great height. Explain this phenomenon and investigate how relevant parameters affect the pumping height.
维尔茨泵是一个垂直安装的空心螺旋装置。它被设计成每转一圈,一端就会浸入水中一次,而另一端(螺旋的中心)则连接到一个垂直的管子上。当旋转时,它可以用来将水抽到很高的高度。解释这一现象并研究相关参数如何影响抽水高度。
