ace is depressed. The fact expressed by this equation, namely, that the eleva-tion is inversely as the diameter of the tube, was one of thefirst observed laws of capillarity. The calculation of the rise of a liquid between parallelplates is quite similar to that for tubes. If I be the length of the… … (6) h = dP9 When two glass plates are moistenedwith water and then brought togetheralong a vertical edge, as in Fig. 109,the liquid appears bounded by a curvewhose equation may be thus found :Let y denote the ordinate of any pointin the curve, let x be the distance ofthe point from the common edge,…
