Explain in your own words: (a) what is the mode of heat transfer through a large steel plate that has its surfaces at specified temperatures? (b) what are the modes when the temperature on one surface of the steel plate is not specified, but the surface is exposed to a fluid at a specified temperature.

GIVEN

(a) Steel plate with specified surface temperatures

(b) Steel plate with one specified temperature and another surface exposed to a fluid

FIND

(a) Modes of heat transfer

SKETCH


(a) Since the surface temperatures are specified, the only mode of heat transfer of importance is
conduction through the steel plate
(b) In addition to conduction to the steel plate, convection at the surface exposed to the fluid must be
considered
