An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 103 kPa and 27°C, and 1850 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Accounting for the variation of specific heats of air with temperature, determine (a) The maximum temperature and pressure that occur during the cycle (b) The net work output (c) The thermal efficiency
