Heat is uniformly generated at the rate of 2 x 105 W/m 3 in a wall of thermal conductivity 25 W/m ∙ K and thickness 60 mm. The wall is exposed to convection on both sides, with different heat transfer coefficients and temperatures as shown. There are straight rectangular fins on the right-hand side of the wall, with dimensions as shown and thermal conductivity of 250 W/m ∙ K. What is the maximum temperature that will occur in the wall?

L= 20 mm 1= 2 mm k= 25 W/m-K 4 =2 x 10Wima h - 50 W/m2-K T= 30°C hz- 12 W/m2-K T2= 15°C 8=2 mm 2L = 60 mm k= 250 W/m-K
