Someone has suggested that the air-standard Otto cycle is more accurate if the two polytropic processes are replaced with isentropic processes. Consider such a cycle when the compression ratio is 8, P₁ = 95 kPa, T₁= 15°C, and the maximum cycle temperature is 1800°C. Determine the heat transferred to and rejected from this cycle, as well as the cycle's thermal efficiency. Use constant specific heats at room temperature. The properties of air at room temperature are cp=1.005 kJ/kg-K, cy=0.718 kJ/kg-K, R = 0.287 kJ/kg-K, and k=1.4. The heat transferred to this cycle is The heat rejected from this cycle is The thermal efficiency is %. kJ/kg. kJ/kg.
