Show Power of Water nave you ever tried to divert a flow of water from a tap or nozzle? Try it when there is considerable pressure pres-sure behind the flow, and you will probably be much surprised with the result of the experiment. Water has a power we ofien fail to appreciate. The pressure on some of the big water wa-ter power projects is so great that a powerful man swinging a four-pound ax with all his might cannot make a dont in the water as it emerges from the nozzle. The ax, no matter how-keen how-keen an edge it may have, is whirled from the hand of the most strenuous ax man at the instant it strikes the stream of water. It has the same effect ef-fect on one's lingers as a rough emery wheel, and will shave a plank with the nicety of a razor edge plane. |
