A shell and tube heat exchanger is indeed a vital component in industrial applications for transferring heat efficiently. Here’s a breakdown of how it works: • Construction: The device consists of a cylindrical shell (the outer vessel) and multiple tubes inside it. One fluid flows through the tubes (tube-side fluid), while the other flows around the tubes inside the shell (shell-side fluid). • Heat Transfer: Heat is transferred between the two fluids through the tube walls. The hot fluid transfe
