...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... | |

...result of rarefying the air in the suction and piston barrels at each stroke of the piston will be, that the pressure of the atmosphere on the surface of the water outside the suction pipe will force the water up into it until it rises as high as the piston, in the... | |

...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 above it... | |

...body of the pump; supposing that after every elevation of the piston there is an equilibrium between the pressure of the atmosphere on the surface of the water in the reservoir, and the elastic force of the rarefied air between the piston and surface of the column... | |

...is 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, thns raised... | |

...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... | |

...the 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 wa.ter 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 same means of producing... | |

We know now that the underlying principle is the same as in a mercurial barometer : it is the pressure of the atmosphere on the surface of the water in the well that pushes the water up into the pump.
