Air undergoes an Ericsson refrigeration cycle, which is the reverse of the Ericsson power cycle introduced in Sec. 9.8.4. Figure P10.58 provides data for the cycle operating at steady state. Sketch the p-y diagram for the cycle and determine the

(a) Heat transfer for the isothermal expansion, per unit mass of air flow, in kJ/kg.

(b) Net work, per unit mass of air flow, in kJ/kg.

(c) Coefficient of performance.
