Abstract :Abstract-In this paper a Double pipe Heat exchanger is designed and fabricated with 1.8m long copper pipe and galvanized iron pipe is utilized for tube and shell materials. The Experimental analysis is conducted by passing hot water in inner pipe and cold water in the annulus. The experiment is performed with both parallel and counter flow configurations under three mass flow rates conditions where cold water flow rate and hot water flow rate are changed. Inlet and Outlet temperatures are measured by using thermocouples at various locations. The Overall heat transfer coefficient is calculated and compared with both parallel and counter flow for theoretical and actual performance of heat exchanger and found counter flow heat transfer is increased than parallel flow. The research takes in to account of different nano fluids for effective heat transfer in Heat exchanger.
