Consider a fin on the condenser of a refrigerator. Generally, these are wires that are connected to a hot tube at both ends. Consider such a wire with a length of 0.1 m and a diameter of 1.0 mm. The base temperature is 35oC with an ambient temperature of 20oC. The convection coefficient is h = 10 W/(m2 oC). On a single plot, plot the temperature profile of the fin, T(x), for the following fin materials: aluminum, AISI 1010 steel, AISI 316 stainless steel, and copper.
