Solved: Determine the percentage increase in heat transfer
Chapter , Problem 3.155(choose chapter or problem)
Determine the percentage increase in heat transfer associated with attaching aluminum fins of rectangular pro- file to a plane wall. The fins are 50 mm long, 0.5 mm thick, and are equally spaced at a distance of 4 mm (250 fins/m). The convection coefficient associated with the bare wall is 40 W/m2 K, while that resulting from attachment of the fins is 30 W/m2 K
