Aluminum fins (k = 170 W/m-K) with triangular profiles shown in Figure P13-42 are used to remove heat from a surface with a temperature of 200 oC. The temperature of the surrounding air is 10 oC. The natural convection coefficient is h = 25 W/m2 -K. Determine the temperature distribution throughout and the heat loss from a typical fin.
