In a Dual cycle, the volume at the end of the isentropic compression is 0.07 L and the pressure at the beginning of the compression stroke is 1 bar. If the swept volume of the cycle is 0.78 L, the pressure ratio during the constant volume heat addition process is 1.9, the volume ratio during the constant pressure heat addition process is 2.1, the specific heat ratio is y=1.3 and the total heat added is 949.7 kJ/kg, the work done in kJ per kg of air is:
