A straight, rectangular aluminum fin k=200 W/m? ^? C , 3.0 mm thick and 7.5 cm long, protrudes from a wall, as shown in the figure below. The base is maintained at 300 ^? C , and the ambient temperature is 50 ^? C with h=10 W/M2? ^? C . Calculate the heat loss, q _f . from the fin per unit depth of the fin. Assume an insulated tip condition with w ? t.
