An air-standard Diesel cycle absorbs 1500 J mol-1 of heat (step DA of Fig. 8.10, which simulates combustion). The pressure and temperature at the beginning of the compression step are 1 bar and 293.15 K (20°C), and the pressure at the end of the compression step is 4 bar. Assuming air to be an ideal gas for which Cp = (7/2)R and Cv = (5/2)R, what are the compression ratio and the expansion ratio of the cycle?
