An air-standard Diesel cycle has an MEP of 592.53kPa. Air is at 300 K and 100kPa before compression and 660 K at the end of an isentropic compression. The heat of 725.5 kJ/kg transfers to the air during the heat addition process. Accounting for the variation of specific heats with temperature, determine the following: (a) the compression ratio, r, and cutoff ratio, rcutoff , (b) the net amount of work derived by the engine, wnet , (c) the heat rejection per unit mass, qout (d) the maximum temperature of the air, Tmax, and (e) the thermal efficiency, ηTH.
