Heat exchanger duty calculation is a fundamental task in process engineering, serving as the primary method for determining the thermal energy transfer rate required to achieve a specific temperature change in a process fluid. This calculation is critical for the sizing, selection, and performance evaluation of shell-and-tube heat exchangers. By establishing the heat duty, engineers can determine the necessary surface area and overall heat transfer coefficient to optimize energy consumption.
