Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

A wall is constructed of a section of stainless steel [k=16 W/m. C] 4.0 mm thick with identical layers of plastic on both sides of the steel. The overall heat-transfer coefficient, considering convection on both sides of the plastic, is 120W / (m ^ 2) * 9 If the overall temperature difference across the arrangement is 60 degrees * C , calculate temperature difference across the stainless steel.
