A two fluid heat exchanger has 2 kg/ liquid ammonia at 20°C, 1003 kPa entering state 3 and exiting at state 4. It is heated by a flow of 1 kg/ nitrogen at 1500 K, state 1, leaving at 600 K, Find the total rate of heat transfer inside the heat exchanger. Sketch the temperature versus distance for the ammonia and find state 4 (T, v) of the ammonia.
