substance in passing from W to X is dQ = cpdt + mdp, (230) and that rejected from Z to Y is dQ = cpdt -f- *#dp (231) The required condition will be fulfilled by making equa-tion (230) equal to equation (231), so that mdp = mdp. Substituting for m from equation (53) gives (dv\ ©*-( dV\ M Deducing… … That is, the required relation is that the ratio of the pressuresat the points cut by any isothermal from the paths DA andBC must be constant.
