: An ideal air-standard Otto cycle engine has a compression ratio of 8. At the beginning of the compression process, the working fluid is at 100 kPa, 27°C, and 800 kJ/kg heat is supplied during the constant volume heat addition process. Sketch the P-Vand T-S diagrams for this cycle and determine the following: a) The temperature and pressure of the air at the end of each process; b) The net work output/cycle [kJ/kg]; c) The thermal efficiency, and d) The mean effective pressure.
