Nitrogen gas at 300 K flows into a well-insulated device operating at steady-state. There is no power supply to this device. The device has two exit streams, 2/3 of the nitrogen (by mass) leaves at 400 K and 1 bar. The remainder of the nitrogen also leaves at 1 bar. What is the temperature of this other exit stream? What is the minimum pressure of the entering stream? Assume ideal gas behavior with Cp = 29 J/mole K.
