Which of the following statements are correct about the below heat exchanger? NOTE: Cold fluid in tube and Hot fluid in the shell.

Which of the following statements are correct about the below heat exchanger? NOTE: Cold fluid in tube and Hot fluid in the shell. Correct Answer The temperature of the fluid in the tube reaches a maximum and then decreases

The cold fluid first comes directly in contact with the hot fluid, they exchange a large amount of heat in this region and the hot fluid in further contact with more cold fluid gets much cooler by the time the tube fluid returns to the shell in 2nd pass. Hence the temperature of the fluid in the tube reaches a maximum when it completes its 1st pass.
