Using p – v – T Data

The following table lists temperatures and specific volumes of ammonia vapor at two pressures:

Data encountered in solving problems often do not fall exactly on the grid of values provided by property tables, and linear interpolation between adjacent table entries becomes necessary. Using the data provided here, estimate

(a) the specific volume at T = 120°F, p = 54 lbf/in.², in ft³/lb.

(b) the temperature at p = 60 lbf/in.², v = 5.982 ft³/lb, in °F.

(c) the specific volume at T = 110°F, p = 58 lbf/in.², in ft³/lb.
