emperature of saturation for its pressure. Having thesedata, we can solve numerically the following problem :— Proposition XIX.—Problem. To draw the curve of free expansion forvapour nascent under a given pressure. (Solution.) In Fig. 24, let AB, parallel to OX, be the isothermal lineof an… … temperature, and i\ that of unity of weight of the vapour at saturation.Let D F be a line drawn parallel to 0 X, at a distance representing anylower pressure P2 corresponding to the temperature r0. It is required tofind the point where the curve of free expansion drawn from B inter-sects DF. Let…
