Abstract
This project is mainly focusing on designing one type of a heat exchanger which is shell and tube heat exchanger. Step by step on designing, the software is build first to make the work on calculation easy and simple by using ε-NTU method. This method technically more simple than LMTD where it has to refer to a complex graph to calculate certain outputs that needed. The software used is Visual Basic. The language in the program consists of formulas of calculating parameters in heat exchanger such as heat transfer coefficient, heat transfer rate or heat capacity rate. This program design should match the heat exchanger software in the market. To design this heat exchanger, many considerations were taken. The shell size must be adaptable to the water flow rate. To determine how many tubes that are used also depends on the size of the shell. Water flow rate can be determined by using ball valve opening. The opening is decided to be 50%, 60%, 65%, 75% and 100%. To read the temperature, a thermometer digital is attached at inlet and outlet for both hot and cold fluid. The five readings were taken and take into calculation using the software that has been build. The manual calculation is done to check the program in the software whether it is compatible. From the results obtained, the heat transfer rate rise up when the mass flow rate increased. Lastly the most suitable and economical heat exchanger is decided. And to conclude, the simulation of heat exchanger in the software is compatible with the design as the result is same.
