5. A three-process cycle of an ideal gas, for which cp = 1.064 and c₁ = 0.804 kl/kgm.K, is initiated by an isentropic compression 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 kgm/s, compute (a)QA, (b) WNET, (c) e, and (d) pm.
