A light breeze at 10mi/h blows across a metal building in the summer. The height of the building wall is 12t, and the width is 20ft. A net energy flux of 110 Btu/h*ft^2 from the sun is absorbed in the wall and subsequently dissipated of the surrounding air by convection. Assuming that the air is 80°F and 1 atm and blows across the wall as on a flat plate, estimate the average temperature the wall will attain for equilibrium conditions.
