Abstract-The Heat Exchangers are used to transfer heat between one fluid and another fluid without allowing two fluids to come into direct contact with each other, the fluids may be either liquid or gaseous form. In this paper we are going to perform analysis for tube in tube Heat Exchanger. The availability Analysis involves the identification of the Heat transfer rate, Entropy Generation, Availability loss. In this paper the availability analysis is performed for tube in tube heat exchanger by considering four working fluids, water, N- pentane, Mineral oil, Glycol, with two flow arrangements, parallel flow and counter flow. And the four working fluids are compared each other. After the availability analysis is performed, graphs are drawn for the four working fluids and compared. It seems to be that the water has high heat transfer rate than other working fluids, also the entropy generation and the availability loss is less for the n- pentane, the efficient fluid is n- pentane in this analysis among the four working fluids.
