Tube Side Pressure Drop in Heat Exchanger for Turbulent Flow Formula

What is Shell and Tube heat exchanger?

A Shell and Tube Heat Exchanger is a common type of heat exchanger used in various industrial applications to transfer heat between two fluids. It consists of a large, cylindrical outer shell (usually made of metal) with multiple smaller tubes (also made of metal) running through it. The tubes are arranged in a bundle inside the shell and are typically oriented parallel to the shell's longitudinal axis.

What are the Factors For Tube Side Pressure Drop?

Skin friction/pipe roughness plays a major role in pressure drop of the fluid. The other parameters that results are the contraction of fluid at tube inlet, expansion of fluid at tube outlet and due to continuous directional changes of tube side fluid.
