Required information An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account constant specific heats at room temperature. The properties of air at room temperature are cp = 1.005 kJ/kg-K, cv=0.718 kJ/kg-K, R = 0.287 kJ/kg. K, and k = 1.4. Determine the mean effective pressure for the cycle. The mean effective pressure for the cycle is kPa.
