Question: A coflowing (same direction) heat exchanger has one line with 0.25 kg/s oxygen at 17C, 200 kPa entering and the other line has 0.6 kg/s

A coflowing (same direction) heat exchanger has one line with 0.25 kg/s oxygen at 17°C, 200 kPa entering and the other line has 0.6 kg/s nitrogen at 150 kPa, 500 K entering. The heat exchanger is very long so the two flows exit at the same temperature. Use constant heat capacities and find the exit temperature and the total rate of entropy generation.
