At the beginning of compression of an ideal Diesel cycle the gashas a temperature and pressure of 40⁰C and 90kN/m², respectively. The volume ratio of compression is16:1. The maximum temperature of the cycle is 1400⁰C.Determine, for the cycle,

1. the pressure and temperature at each of the cycle processchange points,                         [8]
2. the work done/kg gas,                                                                                                                        [4]
3. the thermal efficiency,                                                                                                                        [4]
4. the work ratio,                                                                                                                                      [3]
5. the mean effective pressure,                                                                                                             [3]
6. the Carnot efficiency within the cycle temperature limits.                                                        [3]

Take, γ=1.4 , cp = 1.004 kJ/kg K.
