it fills the rest of the tube c and a portion of d. Suppose b and c to have the same diameter, which is n times that of d.When the column of mercury in b sinks through x millimetres, the level ofthe mercury in c rises just as much, while the coloured liquid rises 7ix- milli-metres, and therefore… … gravities of mercury and the liquid. Accordingly, when the mercury in b sinks x millimetres. y = 2x+ ■ X s is the height of the column of mercury, which corre-sponds to the decrease of atmospheric pressure. Fromthis we have 2S + }l-\ Thus, if the section of the tubes b and c is 20 timesthat of d,…
