Calculate the work done and the final temperature for the following processes:
a. Polytropic, n = 1.1, 4.0 lbm of Air, T1 = 1300 °F, v1=6.519 ft3/lbm. The pressure decreases to half the initial pressure during the process.
b. Polytropic, n = 1.0, 4.0 lbm of Air, T1 = 1300 °F, v1=6.519 ft3/lbm. The pressure decreases to half the initial pressure during the process.
c. Polytropic, n = 1.4, 4.0 lbm of Air, T1 = 1300 °F, v1=6.519 ft3/lbm. The pressure decreases to half the initial pressure during the process.
