Not illustrated. 1838 Excerpt: ...second, will raise about 4 gallons to that height every minute. In the lower part of the figure, c is a valve opening downwards, and this remains open, and permits the water to escape for an instant, when it suddenly closes by the force of the current. The stream being thus interrupted, its momentum opens the valve e, and a quantity of water rushes into the air vessel, the upper part of which receives the pipe, d, through which the water is thrown to the height required. The valve, e, opens upward, so that the water cannot again return to the tube. We suppose, now, that the water in the tube is still, and therefore the current which closed the valve, c, has ceased; consequently the valve, being constructed for such a purpose, falls down by its own weight and the stream begins again to flow; this gives momentum to What is said to be the comparative force of a pipe of water when suddenly checked? What must be the size and length of the pipe, and the height of the source, in order to throw water 40 feet high by means of the water-ram? Explain the action of the water-ram and show why the fluid is thrown up the tube 1 the whole column of water, which again closes the valve, and throws the water into the air vessel as before, and so on, alternately and perpetually. The use of the air vessel into which the wateris thrown, is to give, by its elasticity, a constant pressure on the water in it, and thus to force it in a continued stream through the pipe, the end of which dips into its upper surface. This machine may be made at a small expense, and where only a small quantity of water is wanted, answers a good purpose. PNEUMATICS. This term comes from the Greek word pneuma, which signifies breath or air. It is that science which treats of the equilibrium and motion of...
