The conditions at the beginning of compression in an air-standard Diesel cycle are fixed by P1 =
200 kPa, T1 = 380K. The compression ratio is 20 and the cutoff ratio is 1.8. For k =1.4, determine:
(a) the maximum temperature, in K; (b) the heat addition per unit mass, kJ/kg; (c) the net work
per unit mass, kJ/kg; (d) the thermal efficiency; (e) the mean effective ratio, in kPa; (f) to
investigate the effects of varying compression ratio on the thermal efficiency, plot the thermal
efficiency for compression ratios ranging from 5 to 25.
