%X Heat exchangers have its major application in
automobile, air condition, refrigerator, power plants, and many others. Heat
transfer characteristics and performance of Copper spiral heat exchanger are
investigated and compared with pure water. Nanofluid can enhance
thermos-physical properties. Experiment is carried out for water based SiO<sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> Nanofluid with 15</span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:Verdana;\">nm average sized
nanoparticle at varying air velocity and mass flow rate of fluid to investigate
its effect on heat transfer coefficient. From the experimental data, a closed
form solution for Nusselt number has been calculated using <span style=\"white-space:nowrap;\">&amp;#8712;</span></span><span style=\"font-family:Verdana;\">-NTU method. A new correlation has been proposed as
a function of Reynolds number and Prandtl number. The heat transfer rate,
effectiveness</span><span style=\"font-family:Verdana;\">,</span><span style=\"font-family:Verdana;\"> has been significantly higher compare</span><span style=\"font-family:Verdana;\">d</span><span style=\"font-family:Verdana;\"> to pure water and with increasing volume fraction of nanoparticles.</span>
