Question
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.
