...otherwise leave void. But, on the contrary, if the uppermost vessel be open, during the agitation, the pressure of the atmosphere on the .surface of the water in that vessel, will force the water down into the middle one, as fast as the absorption of the fixed...

...shorter, and therefore will, by its own gravity, run out at c, leaving a vacuum from D to E, did not the pressure of the atmosphere on the surface of the water in the jar force it up the leg DE, and thus continually supply the place of the water in D c. Charles....

...the bucket goes within that distance from the well, the water will never get above it. Now, as it is the pressure of the atmosphere on the surface of the water in the well, that causes the water to ascend in the pump, and follow the piston or bucket, when the air...

...determine the height to which the water will rise after one motion of , the piston ; the fixed sucker being placed at the junction of the suction-tube and...tube, together with the weight of that column. Let ab be the surface of the water in the suction-tube, after the first stroke of the piston : if the piston...

...necessarily formed in ihr receiver. Recurring to the action of the common pump, we shall «ее that the pressure of the atmosphere on the surface of the water in the well, will now force a stream up the rising pipe, and occupy the receiver. The quantity of water,...

...cylinder and boiler. Then, turning the cock W, the weight of the water in the pipe P, aided very soon by the pressure of the atmosphere on the surface of the water in the cistern O, produces a jet within the cylinder, which, dashing against the piston, is dispersed...

...cool air will reconvert the steam in the tube to liquid, and a vacuum will thus be produced so that the pressure of the atmosphere on the surface of the water in the basin will force the water up in the tube, and it will rush up with considerable force, and fill...

...was prevented from entering, by the circumstance of the valve opening outwards ; and, consequently, the pressure of the atmosphere on the surface of the water in the well or reservoir, forced it up into the vessel or tube. Shortly after this, Newcomen used the...

...pump, at the same time a similar operation is going on in the pipe r, for the valve t, being opened, the pressure of the atmosphere on the surface of the water in the cistern s, forces a portion of that water up the pipe r ; and it is important that the vacuum formed...
