a mechanical engineer has approached your boss with a design for a new device. The device is fed with 10mol/min of nitrogen at 29.73 degrees C and 34 bar. The mechanical engineer claims that, when the device is operated in a room at 20 degrees C half of the entering N2 leaves at 40 degrees C and 1 bar and the other half leaves at 0 degrees C and 1 bar. No work is done on or by the nitrogen. Assume Cp is constant at 3.6R. Determine the rate at which heat is expelled by the device
