THERMODYNAMICS An ideal dual cycle has a compression ratio of 14. At the start of the compression process, air is at 100 kPa and 300 K, and at 2200 K at the start of the heat addition phase. Heat transfer to air occurs in two stages, one at constant volume and one at constant pressure, and totals 1520.4 kj/kg. Determine the temperature after the isentropic expansion process, the proportion of heat transferred at constant volume, and the thermal efficiency of the cycle using changing specific heats for air.
