In this experiment, our aim is to demostrate the working principles of concentric tube heat exchanger operating under paralel and counter flow conditions and the observe the effect of flow rate and hot water temperature variation the performance charasteristics of a concentric tube heat exhanger.

A heat exchanger is used when it is necessary to transfer heat from one fluid to another without mixing the fluids. Two types of heat exchangers, parallel flow and counter flow, will be examined in this lab. The parallel flow heat exchanger has the hot and cold fluids flowing in the same direction whereas the two fluids flow in the opposite direction with a counter flow exchanger. The effect of flow rate variation on the performance characteristics of a counter flow heat exchanger will be studied also.
