Problem 2.70

Air expands adiabatically in a pistoncylinder assembly from an initial state where p1 = 100 lbf/in.2 , 1 = 3.704 ft3 /lb, and T1 = 1000 8R, to a final state where p2 = 50 lbf/in.2 The process is polytropic with n = 1.4. The change in specific internal energy, in Btu/lb, can be expressed in terms of temperature change as Du = (0.171)(T2 2 T1). Determine the final temperature, in 8R. Kinetic and potential energy effects can be neglected.
