...friction, and of the elasticity of the uncondensed steam." To this should be added, for each forcing pump, the weight of a column of water whose base is equal to the sectional area of the plunger and altitude to the mean height of the bottom of the plunger above the...

...water from the valve в to the surface of the water in the tube СЕ. То estimate this, we must täte the weight of a column of water whose base is equal to the area of a section of the piston, and whose height is equal to that of the surface of the water above...

...height is the difference between thirty-four feet and 34— A feet ; that is, the effective force is h feet. Thus it appears, that it requires a force to...weight of a column of water, whose base is equal to lie section of the piston, and whose height is that of the water in the suction pipe, above the level...

...height is the difference between thirty-four feet and 34—A feet; that is, the effective force is h feet. Thus it appears, that it requires a force to lift the piston exactly eqqal to the weight of a dolumn of water, whose base is equal to the section of the piston, and whose...

...therefore as the square of its velocity. The impulse of water against a plane surface is an equivalent of the weight of a column of water whose base is equal to the transverse section of the stream, and twice the height belonging to its velocity. If the aperture is...

...the same amount of pressure. Hence the pressure on the bottom of a vessel containing water is equal to the weight of a column of water whose base is equal to the bottom of the vessel, and its height equal to the depth of the bottom from the surface of the water...

...inserted. Let the vessel and the tube be filled with water. The pressure on the bottom, BC, will be equal to the weight of a column of water whose base is equal to the area of the bottom, BC, and whose height . is GK ; that is, it is equal to the weight of a quantity...

...pressure upon the side. Hence the total pressure upon the side of a vessel containing water will be equal to the weight of a column of water whose base is equal to the area of that side, and whose height is equal to one half the depth of the liquid in the vessel, or,...

...pressuro upon the side. Hence the total pressure upon the side of a vessel containing water will be equal to the weight of a column of water whose base is equal to the area of that side, and whose height is equal to one half tho depth of tlio liquid in the vessel, or,...

...whose height is the difference between thirty-four feet and 34— A feet ; that is, the effective force is A feet. Thus it appears, that it requires a force...piston, and whose height is that of the water in the suction pipe, above the level of the water in the well. It follows, therefore, that as the water rises...
