...required at each stroke to lift the piston. The column of water discharged at each stroke, is equal to a column of water, whose base is the section of the piston, and whose altitude is the length of the stroke. The quantity may therefore be found, in cubic feet, by multiplying... | |

...ascending column. Hence it appears, that the pressure exerted by the water in PV on the lower surface of the piston is equal to the weight of a column of water whose base is equal to the section of the piston, and whose height is MN. This, therefore, is the force to be overcome... | |
