and incompressible—andbecause of tlie cliaracter of the problems presented, it is customaryand convenient to consider the energy of water as capable of existingin three forms—Pressure, Velocity, and Gravity. Thus, in Fig. 2,with the conditions as represented (see also Hydraulics, page 34),if the… … _55i- Fig. 2. Illustrating Relations of Pressure-. Velocity-, and Crravity-Head. feet. Now, if the valve at D be partially opened, so that there issome velocity of flow i\, in the pipe at section C, the column of waterin the tube CC will sink to some lower level, as CC\ and the pressurein the pipe…
