In an ideal gas refrigeration cycle, air enters the compressor at 12°C, 50 kPa and enters the turbine at 47°C, 250 kPa. The mass flow rate of air through the cycle is 0.08 kg/s. Assume variable specific heats for air and consider ideal gas properties of air as given in table.
What will be the rate of refrigeration (in kW)? (Answer up to two decimal places)
    Correct answer is '6.67'. Can you explain this answer?

    We assume both the turbine and the compressor to be isentropic. The turbine inlet temperature to be the temperature of the surroundings and the compressor inlet temperature to be the temperature of the refrigerated space.
    At T1 = 285 K; h1 = 285.14 kJ/kg and pr1 = 1.1584.
    We interpolate the value of h2 from the date given in table, corresponding to the value of pr2 = 5.792, as
    At T3 = 320 K; h3 = 320.29 kJ/kg and pr3 = 1.7375.
    Now the value of h4, corresponding to the value of pr4 = 0.3475, is
    = 201.76 kJ/kg
    Then the rate of refrigeration is,
