Question 1 Research has shown that the air-standard Otto cycle is more accurate when the two isentropic processes are replaced with polytropic processes with a polytropic exponent n=1.4. Consider such a cycle when the compression ratio of 9, P=85 KPa, T=25°C, and the maximum cycle temperature is 1250°C. Determine: (a) The heat transferred to and rejected from this cycle. (b) The cycle's thermal efficiency. Use constant specific heats at room temperature.
