The compression occurs in two stages, with each stage being a polytropic process with n = 1.27. The air is cooled to 80°F between the stages by an intercooler operating at 45 lbf/in2.

One mole of an ideal gas, initially at 20 °C (293.15 K) and 1.50 bar, undergoes the following mechanically reversible changes. It is compressed isothermally to a point such that when it is heated at constant volume to 100 °C (373.15 K) its final pressure is 10 bar. Take Cp = (7/2)R and Cv = (5/2)R. Hints: Process 1 to 2: T1 = T2; Process 2 to 3: (P2/T2) = (P3/T3), thus (P2/T1) = (P3/T3) Use equations for isothermic and isochoric processes. Wtotal = W12 + W23 and Qtotal = Q12 + Q23. What is the change in internal energy? What is the change in enthalpy?
