Air at the beginning of an ideal Otto cycle is at 101.3 kPa and 15°C. The cycle has a compression ratio of 7, and 1000 kJ/kg of heat is transferred to air during the constantvolume heat-addition process. Using constant specific heats at room temperature, calculate, 1.1 the pressure and temperature at the end of the heat- addition process, 1.2 the net work output, 1.3 the thermal efficiency, and 1.4 the mean effective pressure for the cycle.
