3. An ideal Otto cycle has a compression ratio of 6. At the beginning of the compression process, air is at 230 kPa and 22°C, and 1200 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Assuming the variation of specific heats of air with temperature. Determine; a. The maximum temperature and pressure that occur during the cycle, in K and kPa, respectively. b. The net work output, in kJ/kg, c. The thermal efficiency, d. The mean effective pressure for the cycle, in kPa.
