W/m-°C) is attached to a hot surface of 100°C. The convection heat transfer coefficient

is 15 W/m²-°C and the surrounding air is maintained at 30°C. a. Assume a very long fin

and calculate the rate of heat transfer from the fin. b. Is the assumption from part a.

valid? Why? c. Find the heat transfer using an alternative method. Assume no radiation

heat transfer.
