Abstract: The transfer of heat to and from process fluids is an essential part of most of the chemical processes. Therefore, heat exchangers (HEs) are used extensively and regularly in process and allied industries and are very important during design and operation. The most commonly used type of HE is the shell and tube heat exchanger. In the present study, a comparative analysis of a water to water STHE wherein, hot water flows inside the tubes and cold water inside the shell is made, to study and analyze the heat transfer coefficient and pressure drops for different mass flow rates and inlet and outlet temperatures, using Kern, Bell and Bell Delaware methods. This paper purely aims at studying and comparing different methods of STHE and bringing out which method is better for adopting in shell side calculations.
