At the beginning of the compression process of a standard cold air Otto cycle, the air is at 100 kPa, 25 ° C and 1200 kJ / kg of heat is added during the constant volume heat addition process. If the compression ratio is 7.5, determine the following: a) The maximum temperature and pressure of the cycle. b) The net output work. c) Thermal efficiency and mean effective pressure.
