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. 1. Report the temperature after compression in K. 2. Report the cutoff ratio to two decmial places using rounding. 3. Report the amount of heat added to the cycle in kJ/kg to one decimal place using rounding. 4. Report the temperature after isentropic expansion in K to one decimal place using rounding. 5. Report the amount of heat rejected in kJ/kg rounded to one decimal place. 6. Report the net work produced in kJ/kg to the nearest whole number using rounding. 7. Report the overall thermal efficiency as a percentage (0 to 100) to one decimal place using rounding.
