Constant Specific Volume Lines:
The constant specific volumes lines are inclined obliquely straight lines & regularly spaced as illustrated in fig. These lines are sketch up to the saturation curve. To set up points on a line of constant specific volume, 0.90 m3/kg for instance, from the perfect-gas equation, the specific volume v is following

put 0.90 for v, the barometric pressure for pt, & at arbitrary values of T solve out for ps. the pairs of ps and t values then explained the line of constant v.
