quid by the method ofbalancing. This method is basedon the laws of liquid pressure.Suppose we have two tubes, con-nected as at a in Fig. 65. Poursome liquid into one tube, and aliquid that will not mix with itinto the other. Then, when theliquids have come to rest, we shallhave two columns… … 104 DENSITY AND SPECIFIC GRA VITY. liquids have come to rest, we know that these pressures areequal. Call the upward pressure P, and the downwardpressure P; then P = P\ But we know that and P = aX D X A,P> = a X D X A, calling a, D, and A the values for the second liquid. So aXDx A = a xD X A\…
