In case of a multipass shell and tube heat exchanger, the temperature drop in the fluid

Question

Quizplus · Accepted Answer

The temperature drop in a fluid and across the wall in a shell and tube heat exchanger is proportional to the individual resistances to heat transfer. This is because, according to the heat transfer principles, the rate of heat transfer (Q) is directly proportional to the temperature difference (ΔT) and inversely proportional to the resistance (R), as given by Q = ΔT/R. Therefore, the temperature drop across different sections (fluid or wall) is proportional to the resistances encountered in those sections.
