An ideal, air-standard Diesel cycle has a compression ratio of 20. The maximum temperature is 2200 K while the air is 320 K and at 105 kPa before compression. Assume that specific heats vary with temperature. a) Report the temperature after isentropic expansion in K to one decimal place using rounding. b) Report the net work produced in kJ/kg to one decimal place using rounding. c) Report the overall thermal efficiency as a percentage (0 to 100) to one decimal place using rounding.
