The state at the beginning of compression of an air-standard Diesel cycle is fixed by p = 100 kPa and T = 310 K. The compression ratio is 21 and the cutoff ratio is 1.9. Determine: (a) the maximum temperature, in K. (b) the pressure at the end of the expansion, in kPa. (c) the net work per unit mass of air, in kJ/kg. (d) the percent thermal efficiency.
