This paper revel's the heat transfer characteristics, flow friction characteristics, of a horizontal tube-in-tube heat exchanger for single phase heat transfer with water as the working fluid. The material used for the construction of heat exchanger is copper, owing to its high thermal conductivity. The various techniques for achieving improved heat transfer are usually referred to as "heat transfer augmentation" or "heat transfer enhancement" and the heat exchanger provided with heat transfer enhancement techniques as "Augmented Heat Exchanger". The objective is to reduce as many of the factors as possible capital cost, power cost, maintenance cost, space and weight, consistent with safety and reliability. Paper describes the principal techniques of industrial importance for the augmentation of single phase heat transfer on the inside of tubes namely "Micro fin". So micro fins should be used in heat exchanger when high heat transfer rate is required and pressure drop is of no significance. The obtained results show that the Nusselt number in the tube with the micro fin increases. It was observed that, based on constant flow rate, the heat transfer rates for finned heat exchanger were found to be more than the plain tube.
