Required information An ideal Otto cycle has a compression ratio of 8 . At the beginning of the compression process, air is at 95kPa and 27C, and 730kJ/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=1.005kJ/kgK,cV=0.718kJ/kgK,R =0.287kJ/kgK, and k=1.4 Determine the thermal efficiency. (You must provide an answer before moving on to the next part.) The thermal efficiency is
