A straight fin of rectangular profile has a thermal conductivity of 14 W/m ∙ ºC, thickness of 2.0 mm, and length of 23 mm. The base of the fin is maintained at a temperature of 220ºC while the fin is exposed to a convection environment at 23ºC with h = 25 W/m2 ∙ ºC. Calculate the heat lost per meter of fin depth.
