A longitudinal aluminum fin (k = 230 w/mk) is attached to a copper tube having an outside radius of 0.04m. The length of the fin is 0.080 m and the thickness is 3mm. The tube base is held at 450 K and the external surrounding air at 300 K has a convective coefficient of 25 w/m^2 K. Calculate the fin efficiency and the heat loss from the fin per 1.0 m of length.
