The following table lists temperatures and specific volumes of ammonia vapor at two pressures P= 50 psi P= 60 psi

T (°F)   v(ft3/lbm)   T (°F)    v (ft3/lbm)
100        6.836       100         5.659
120        7.110        120        5.891
140        7.280       140         6.120

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

a) The specific volume at T = 120°F, P = 57 psi in ft3/lbm
b) The temperature at P = 60 psi, v= 5.96 ft3/lbm, in °F
c) The specific volume at T = 133°F, P = 56 psi in ft3/lb
