Abstracts: More than 65% of the market share (in the late 1990s) in process and petrochemical industry heat exchangers is held by the shell-and-tube heat exchanger, for the following reasons: its versatility for handling a wide range of operating conditions with a variety of materials, design experience of about 100 years, proven design methods, and design practice with codes and standards. Shell and tube heat exchanger is widely used in many industrial power generation plants as well as chemical, petrochemical, and petroleum industries. In the present work, a shell and tube heat exchanger design and the heat transfer coefficient and pressure drop on the shell side and tube side of a shell-and-tube heat exchanger have been experimentally obtained for MS tubes. Some geometrical parameters of the shell and tube heat exchanger are taken as the design, variables such as tube inside diameter, tube outside diameter, tube pitch, and number of tubes and baffle spacing etc. In this work the ms material used for tube and shell and tube heat exchanger. In this work find out the overall heat transfer co-efficient by using different heat exchanger analysis method. The experimental analysis of shell and tube heat exchanger is reported in this work. In this experimental work we have using water fluid and water as a fluid. Testing of shell and tube heat exchanger is reported in this work. The number of tubes and tube side cross section area increased the effectiveness of shell and tube heat exchanger increased. The mass flow rate of water is increased and mass flow rate of water is keeping constant the overall heat transfer co-efficient of shell and tube heat exchanger is increased. This increased the effectiveness of shell and tube heat exchanger. The Nusselt number increased Reynolds. This increased the heat transfer co-efficient of tube side and shell side of shell and tube heat exchanger. The entropy generation number which is the ratio of entropy generation rate and inlet temperature of fluid to the heat transfer rate is taken as the objective function. Therefore the objective is to minimize the entropy generation number to increase the effectiveness of shell and tube heat exchanger having ms as a tube material. We increase the number of tubes by keeping the other parameters constant in the given application of shell and tube heat exchanger which increases the effectiveness of heat exchanger by minimizing the entropy generation number and also reduce the pressure drop on both shell and tube side of shell and tube heat exchanger.
