...stroke. The steam on entering the condenser is met by a jet or spray of water, forced into the condenser by the pressure of the atmosphere on the surface of the water supply outside, through the injection pipe. On the end of the injection pipe is a perforated enlargement,... | |

...was not the cause of the water's risiugto a given height, as was the opinion M that time ; but that the pressure of the atmosphere on the surface of the water in the well caused that water to rise into tlie tube of the pump, and so fill the space which had been... | |

...rose, whose duty it is to scatter, or spray, the injection water that is forced into the condenser by the pressure of the atmosphere on the surface of the water supply outside. The spray coming into direct contact with the incoming steam deprives the steam of... | |

...that the water in the lower part of the pipe s, and in the condenser T, will continue to fall till the pressure of the atmosphere on the surface of the water in the vessel at the bottom of the well Z will support the column of water above it in the pipe Y, and... | |

...could by any means abstract the air from within the tumbler, the water would be forced up into it, by the pressure of the atmosphere on the surface of the water without. Under the circumstances we have mentioned, this event invariably takes place. The air may... | |

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.
