An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at \( 95 \mathrm{kPa} \) and \( 27 \mathrm{C} \), and \( 780 \mathrm{~kJ} / \mathrm{kg} \) 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 \( c_{p}=1.005 \mathrm{~kJ} / \mathrm{kg} \cdot \mathrm{K}, c_{V}=0.718 \mathrm{~kJ} / \mathrm{kg} \cdot \mathrm{K}, R \) \( =0.287 \mathrm{~kJ} / \mathrm{kg} \cdot \mathrm{K} \), and \( k=1.4 \) Determine the net work output, (You must provide an answer before moving on to the next part.) The net work output is \( \mathrm{kJ} / \mathrm{kg} \).
