To determine the overall heat transfer coefficient (U) in the parallel flow heat exchanger


The process of that heat exchange between two fluids  that are at different temperatures and separated by a solid wall occurs in engineering applications. The device used to implement this exchanged is termed as heat exchanger and specific applications may found in power production, waste heat recovery and chemical processing.In a counter flow heat exchanger the hot and the cold fluid moves in the opposite direction in a  concentric tube.
