6. In an air-standard Diesel cycle, the pressure and temperature at the beginning of the compression stroke are 100 kPa and 295 K respectively, and the heat supplied is 1500 J/mol, what are the compression ratio and the expansion ratio of the cycle if the pressure at the end of combustion step is 400 kPa. Assume air to be an ideal gas with Cp = (7/2)R and Cy = (5/2)R.
