where π‘ˆπ‘ˆ is the overall heat transfer coefficient and Ξ± Convection heat transfer coefficient [W/(m 2 K)] A Surface area [m 2] T fluid Fluid temperature [K] T surface Surface temperature [K] Nusselt Number.

Heat Transfer Chapter 8 Using the Overall Heat Transfer Coefficient (U) in Convection Calcs

The overall heat transfer coefficient is a measure of the overall ability of a series of conductive and convective barriers to transfer heat The convection heat transfer coefficient will change along the plane as the flow type changes Heat transfer through a surface like a wall can be calculated as

PPT Heat Transfer Physical Origins and Rate Equations PowerPoint Presentation ID4370026. The values of Ξ± and U for a small element of heat transfer surface are called local ones The flow will start as laminar but can change to turbulent flow if the plate is long enough.
