Q1/An air-standard Diesel cycle absorbs 1500 J-mol-1 of heat. The pressure and temperature at the beginning of the compression step are 1 bar and 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?
