Heat Transfer Coefficient of a Composite Wall
A composite wall generally consists of
When a composite wall of three layers in series having thermal resistances R1, R2 and R3 respectively. The heat transfer takes place normal to the surface of the layers. How is the total thermal resistance of the composite system calculated?
A hot fluid flow inside the tube covered with a layer of thermal insulation is an example of composite system.
Select the only wrong statement.
Heat transfer by conduction is directly proportional to
