This report details a Cross-Flow Heat Exchanger experiment conducted as part of a thermodynamics laboratory. The experiment involves analyzing the convective cooling of a heated rod in a cross-flow setup. The report includes calculations for the density and viscosity of air, and surface area of the rod. It also addresses the determination of flow type based on the Reynolds number, and investigates the effects of rod placement on convective cooling rates, supported by Nusselt number calculations. The report discusses the relationship between rod position, air flow velocity, and the Nusselt number, which is obtained from heat flux equations. The report also includes formulas and calculations for key parameters like the heat transfer coefficient. The report concludes with an analysis of the results and their implications for heat transfer principles.
