A fin of thickness B = 0.6 cm, width W = 3 cm, a length L attached to a plane wall of 10 cm, maintained 200 25 ° fin dissipates heat into ambient air C 0 average heat transfer coefficient C 50 W / m 2 . k. The thermal conductivity of the wing is 54.9 W / mK. Assume no heat loss from the edge of the fins and T = f(z).

Build the model that gives the temperature distribution in the fin.

     B = 0.6cm

What should be the temperature of the wing at z = 4 cm?
