Repeat Problem 9-60 using constant specific heats at room temperature. Is the constant specific heat assumption reasonable in this case?
The compression ratio of an ideal dual cycle is 14. Air is at 100 kPa and 300 K at the beginning of the compression process and at 2200 K at the end of the heat-addition process. Heat transfer to air takes place partly at constant volume and partly at constant pressure, and it amounts to 1520.4 kJ/kg. Assuming variable specific heats for air, determine
(a) The fraction of heat transferred at constant volume and
