This project related to Heat Transfer rate from a cross-flow copper fins and copper-nickel multi-tube can be augmented either by increasing the surface area or by creating the turbulence or by increasing the friction. In the present project, the experimental investigation has been carried out for a specific type of bimetallic finned tube. Bi-metallic finned tube is a tube in which the fins are of a different material than the material of the base tube. The bimetallic finned tube which is being investigated is a copper-nickel tube with copper fins of uniform thickness. The optimum fin may be...
