Question: 14) A coflowing (same direction) heat exchanger has one line with 0.5 kg/s (0.03 mass flow rate0.07kg/s, increment 0.01 kg/s) oxygen at 17C, 200

14) A coflowing (same direction) heat exchanger has one line with 0.5

14) A coflowing (same direction) heat exchanger has one line with 0.5 kg/s (0.03 mass flow rate0.07kg/s, increment 0.01 kg/s) oxygen at 17C, 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. Plot the variation of the exit temperature with changing mass flow rate and discuss the result. Find the total rate of entropy generation. Plot the variation of the total rate of entropy generation with changing mass flow rate and discuss the result. +3
