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) to an external ambient (T.) at 25"C. The convection heat transfer coefficient at the top surface is "h'. The sides (x 0, x a and y=0) are maintained at constant wall temperatures shown below. Show how will you find the temperature at any location T(x,y). Show your working steps clearly (30 points) To= 25"C h, T y =b T - 25"C T(x, y) T - 40"C y=0 X=() T = 80C X= a
