One-tenth kilogram of air as an ideal gas with k 5 1.4 executes a Carnot refrigeration cycle, as shown in Fig. 5.16. The isothermal expansion occurs at 2238C with a heat transfer to the air of 3.4 kJ. The isothermal compression occurs at 278C to a final volume of 0.01 m3. Using the results of Prob. 5.80 adapted to the present case, determine
(a) the pressure, in kPa, at each of the four principal states.
(b) the work, in kJ, for each of the four processes.
(c) the coefficient of performance.
