Total Time: 1 hour 15 minutes Full Marks: 50 (25% of Final Grade) 3. The 2D solid domain shown below has constant thermal conductivity (k), is at steady state and is with no energy generation. Heat is lost by convection from the top (y=b) and bottom (y=0) surfaces to an external ambient (T) at 25C. The convection heat transfer coefficient at the top and bottom surfaces is 'h'. The sides (x=0 and x=a) are maintained at a constant wall temperature of 60C. Show the co-ordinate system you should use to solve the problem below. Show how will you find the temperature at any location T(x,y). Show your working steps clearly. (20 points) T = 25C h, T y=b T=60C T(x,y) y=0 x = 0 h, To T = 25C T=60C x=a 5/11 EML 5152 (Exam 1) - Spring 2023 30
