Article Analysis of a bayonet tube heat exchanger

Thank you Farid Sir and Ebrahim Sir for sharing the links.

Also I have seen  case study on Analysis of a bayonet tube heat exchanger but while i was going through his results it was seen that the heat duty for tubeside and shell side does not match in his own results.

Could you tell what is the reason for that?

Regards
