In a dual cycle, the pressure and temperature at the beginning of the compression process are: 100 KPa and 290 K. During the heat addition process, the first one-third of the total qH occurs at constant volume and the last two-thirds occurs at constant pressure. Assume that the total qH is 2400 kJ/kg, and the compression ratio is 10. Calculate the maximum pressure and temperature and the thermal efficiency of this cycle. Compare the results with those of a conventional Otto cycle having the same given variables.
