An Otto Cycle has air operating as the working fluid. The air begins the compression process at 90 kPa and 40oC. During the heat addition process, the maximum temperature of the air (T3) is 2000oC. The compression ratio of the cycle is 9.2. Treating this as a “Hot Air Standard Cycle”, determine the temperature and pressure at the end of each process, the net work per kg of air produced in the cycle, the thermal efficiency of the cycle, and the mean effective pressure.
