One kilogram of air is taken through a constant volume cycle. Atthe commencement of the adiabatic compression, the pressure andtemperature are 103 kN/m² and 100⁰Crespectively. The adiabatic compression has a volume ratio of 6:1.The maximum pressure of the cycle is 3.45 MN/m².Determine, for the cycle,

1. the pressure, volume and temperature at each of the cycleprocess change points,              [8]
2. the heat transferred to the air,                                                                                                         [3]
3. the heat rejected by the air,                                                                                                              [3]
4. the ideal thermal efficiency,                                                                                                              [4]
5. cyclicwork                                                                                                                                               [4]
6. the mean effective pressure.                                                                                                            [3]

For the air, take, R = 0.287 kJ/kg K, γ=1.4
