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.
