A heat exchanger is a device used to transfer heat between two fluids. The shell and tube heat exchanger consists of two tubes arranged in a single pass. The hot fluid, which is heated water, enters through the lower side of the end box and passes through the tubes in the lower half of the shell. It then changes direction, flows through the tubes in the top half of the shell, and exits at the opposite end. On the other hand, cold water enters the shell's lower section, flows over the tubes and baffles, and exits the shell through an outlet located on the top surface. The water circulating in the tubes acts as the coil fluid.

evaluate and study the heat load and head balance, LMTD and overall heat transfer coefficient.

calculate the Reynolds numbers at the shell and tubes sides.

measure and determine the shell and tube sides pressure drop.
