Lecture 15 : Fins and General Conduction Analysis

[@phalgunissharma-placementc8720]

sir what would be the area in the question

[@arsitech-ltd]

Dear, Its always depends on fins. General term for crossection area mentioned as Ac & for surface area As.

[@NAYAN-t3e]

Here, they assumed that the cross sectional area (Normal to conductive heat flow) is constant along fin length I.e. from base to tip. Hence, the differential equation of heat transfer through fins becomes independent of cross section of fin.
