5. A three-process cycle of an ideal gas, for which c₁ = 1.064 and Cy = 0.804 kJ/kg.Ko, is initiated by an isentropic compres- sion 1-2 from 103.4 kPa, 27°C to 608.1 kPa. A constant volume process 2-3 and a polytropic 3-1 with n = 1.2 complete the cycle. Circulation is a steady rate of 0.905 kg/s, compute (a) QA, (b) W, (c) e, and (d) Pm 101) 15% (d) 1981
