2) Consider a Carnot cycle executed in a closed system with air as the working fluid. The maximum pressure in the cycle is 1300 kPa while the maximum temperature is 950 K. If the entropy increase during the isothermal heat rejection process is 0.25 kJ/kg-K and the network output is 100 kJ/kg, knowing that R= 0.287 kJ/kg.K and y= 1.4 determine the heat rejection from the cycle:
