09) In an air standard Otto cycle the compression ratio is 9:1. Compression begins at 0.95 bar and 17°C. The maximum cycle temperature is 1100°C and Cv=0.718 kJ/kg-K. Calculate the heat supplied per kg air, maximum cycle pressure and temperature, the cycle efficiency and mean effective pressure. Also calculate the efficiency of a Carnot cycle working between the same temperature limits. (Ans 484.7 kJ, 40.50 bar, 571 K, 58.5%,
