show howmuch was spent in doing the external work, i.e.,raising the shaft by the expansion of the water. The absolute pressure corresponding to aboiling-point of 307° F. is 74.5 pounds persquare inch. The total weight of shaft andpiston will be 74.5X144 = 10,728 pounds. By formula, the heat added… … The external work will be 10728 X .00483 778 = .07 B.T.U. which may be neglected. Vaporizing a Liquid at its Boiling-point.—Let heat be addedto the boiling water. We note two effects, (b) and (c): 1. Notwithstanding the addition of heat, the temperature of the water remains constant at 307° F. 164…
