The state at the beginning of compression of an air-standard Diesel cycle is fixed by p₁ = 100 kPa and T₁ = 310 K. The compression ratio is 18 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.

At the beginning of the compression process of an Otto cycle, p1 = 14.7 lbf/in.2 and T1 = 530°R. The maximum cycle temperature is 3000°R. On a cold air-standard basis using k = 1.4, determine the net work developed, in Btu per unit mass of air, the thermal efficiency, and mean effective pressure, in lbf/in.2, for compression ratios of 6, 8, and 10.
