Someone has suggested that the air standard Otto cycle is more accurate if the two isentropic processes are replaced with polytropic processes with a polytropic exponent of n = 1.3. Consider such a cycle when the compression ratio is 8, P 1 is 95 kPa, T1 is 15 C and the maximum cycle temperature is 1200 C. Determine the heat transferred to and rejected from this cycle as well as the cycles thermal efficiency. Use constant specific heats at room temperature. Answers 835 kJ/kg, 420 kJ/kg, 49.8%.
