In the present study the performance of the heat transfer process in a given heat exchanger is determined for longitudinal fin profiles (rectangular). The performance of a double pipe heat exchanger is analyzed in two parts that is optimization and experimentation. In the part of optimization numerical analysis performed by Matlab program. This program will serve to optimize the fin height so as to obtain maximum possible heat transfer without any wastage of material at a given length and inlet

Also all the performance parameter such as efficiency, pressure drop, effectiveness, heat transfer coefficient, outlet temperature of both fluid, overall heat transfer coefficient studied same time for all possible fin height. In second part experimentation is carried out in a counter flow double pipe heat exchanger for varied mass flow rate which ranges from 0.0168 kg/s to 0.0126 kg/s. Experimental results and analytical result shows for optimum height is effectiveness increase up to 23% and heat transfer is enhanced by 26% than unfinned pipe .Also in case of varying mass flow rate for 0.0126 kg/s give good effectiveness and heat transfer than 0.0126 kg/s mass flow rate
