Air in a closed piston-cylinder arrangement is expanded from the initial pressure of 8.9 bar and initial volume of 0.026 m³ to the final state of p2 = 3 bar. A polytropic relation of pV1.26 = constant was followed
between pressure and volume for the process. The specific internal energy at the initial and final states are 155.5 and 100.5 kJ/kg, respectively. The mass of the air is 0.26 kg. Neglecting the effect of kinetic and
potential energy, determine the heat transfer, in kJ.
Answer:
Air is compressed in a piston-cylinder assembly from p₁ = 10 lb-/in², T₁= 500°R, V₁ = 9 ft³ to a final volume of V₂ = 1 ft³ in a process
described by pv¹.30 = constant. Assume ideal gas behavior and neglect kinetic and potential energy effects.
Using constant specific heats evaluated at T₁, determine the work and the heat transfer, in Btu.

Air expands adiabatically in a piston–cylinder assembly from an initial state where p1 = 100 lbf/in.2, v1 = 3.704 ft3/lb, and T1 = 1000 °R, to a final state where p2 = 20 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 Δu=(0.171)(T2 - T1).Determine the final temperature, in °R.Kinetic and potential energy effects can be neglected.
