e lattercylinder is flowing out of thecylinder, and is finished with sofar as the derivation of energy is concerned. Thus there is alwaysat least one piston which is doing work on the crank, and continuousrotation of the shaft D is secured. The horse-power may be calculated in the following manner… … Fig. 293.—Three-cylinder hydraulic engine. Then Resultant force exerted by the water on one piston =p x 7rd2/4 Ib.wt. Work done on one piston per stroke =p-n-d2/i x L foot-lb.As there are three pistons, there will be 3N strokes per minute,during each of which work will be done ; hence Work done per…
