Abstract—The experimental investigation of heat transfer coefficient for Newtonian and non-Newtonian fluids, obeying Power-law, has been carried out by measuring local surface temperature of heated tube and bulk inlet and outlet temperatures of test fluid. The effect of neighbouring tubes was studied by placing dummy tubes around it one by one. Experiment was conducted with single tube and using four more tube arrangements. The following correlation has been obtained for heat transfer for the flow of water, 0.5% PVA and 1% and 1.5% CMC solutions across tube bank.
