細管を用いた高所への揚水方法

In a narrow tube water columns could be maintained with surface tension, and they could be transported to height only with very slow speed, otherwise they were divided into a lot of drops of water. The limited values of velocity were found experimentally at various surface tensions and with various diameters of tube. With a compressed air tank and regulator, air of low pressure and low flow quantity was supplied to transport a water column upward. The methods of connecting a water supply pipe, an air supply pipe and a water column transportation pipe were studied for next water column to be supplied automatically after a water column flew into a collection device. It was confirmed that water could be transported to the height of 60m with this system. This means that we can transport water to height automatically and continually, if we have a bicycle inflator, a pressure vessel and a long narrow tube.
