A rectangular fin (10 cm long, 1 mm thick) is attached to a wall at 423K. The temperature of the air surrounding the fin is 298 K, and the convective heat transfer coefficient is 40 W/m2 K. Find the steady-state temperature profile of the fin by dividing the rod into five equal sized domains, assuming that the heat loss from the end of the fin is negligible. Assume the fin k = 40 W/m-K. Do this again but for 10 equal sized domains.
