Consider a Carnot cycle executed in a closed system with air as the working fluid. The maximum pressure in the cycle is 800 kPa while the maximum temperature is750 K. If the entropy increase during the isothermal heat rejection process is 0.25 kJ/kg * K and the net work output is 100 kJ/kg. Find:a) the minimum pressure in the cycleb) the heat rejection from the cycle
