Question

Heat is uniformly generated at the rate of 2105 w/m3 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 250w/m.K. What is the maximum temperature that will occur in the wall?

Answer 1

Answer:

Heat is uniformly generated at a rate of 2x10^5 W/m^3. In a wall of thermal conductivity k = 25 W/mK and thickness 60mm. The wall is exposed to convection on both sides. There are straight rectangular fins on the right hand side of the wallwith thermal conductivity 250 W/mK. What is the max temp that will occur in the wall? (More givens in the image of the problem)
