Consider an automobile engine which operates on the ideal Ottocycle. In this engine, air is compressed with a compression ratioof 10. At the beginning of the compression process, air is at 105kPa and 17oC, and in the combustion process 640 kJ/kg of heat isadded to air. Taking into account the variation of specific heatswith temperature, determine (a) the pressure and temperature at theend of the heat-addition (combustion) process, (b) the net workoutput, (c) the thermal efficiency of the engine, and show thecycle on a P-ν diagram.
