223. 0.5 kg of air is taken through a constant pressure cycle. At the beginning of adiabatic compression are 96.5 kN/m2 and 15 °C. The pressure ratio of compression is 6. Constant pressure heat addition occurs after adiabatic compression until the volume is doubled. Take y=1.4 and R-0.289 kJ/kg K. Determine for the cycle: (a) The pressure, volume and temperature at cycle state points. (b) The heat received. (c) The thermal efficiency. (e) The heat rejected. (d) The work ratio.
