Extracted text: 100 mole of nitrogen gas (N2) per hour entering a heat exchanger with the temperature of 100°c and leaves the heat exchanger at 20 °c. From the other side water with the temperature of 25 °C enters the heat exchanger and gets warm. i) Sketch the process flowchart and label it. ii) Calculate the amount of heat that N2 gives to the heat exchanger. iii) How much water should enter to the system per hour to reach to the temperature of 90 °C.
