LIQUIDS AND GASES. 53 Case V. — Fill the chimney with water, and invert it over the faceof the gauge, as in Fig. 50. Case VI. — With the form of gauge used in Case I, push thegauge up into the chimney, which is inverted and full of water(Fig. 51), noting any variations of pressure. At what point is… … Fig. 50. Fig. 51. pressure inside the chimney the same as in the open air ? At whatpoint is the pressure less ? How long would the chimney have to be,so that the gauge could be pushed up to a point where there wouldbe no pressure? Where would that point be if the liquid weremercury? 63. Relation of…
