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 250C. 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
