An air-standard Otto cycle has a compression ratio of 6. At the beginning of compression, the pressure is 100 kPa and the temperature is 300 K. During the heating process, the temperature is raised to 2500 K. Assume that the cold air-standard assumption applies and determine:
a) the heat added (in kJ/kg)
b) the net work (in kJ/kg)
c) the thermal efficiency of the cycle
d) the mean effective pressure (in kPa)
