A long duct has a triangular cross-section. The angle between surfaces 1 and 2 is 60deg, and the other two angles are 90deg and 30deg. The width of side 3 is 2 m. all surfaces are black. Surface 1 is insulated and its temperature is maintained at 1050 K. Surface 2 is kept at a constant temperature. The temperature of surface 3 is 680 K. Calculate the rate of heat addition (or removal) needed at surface 2, and find the temperature of this surface. Base your calculations on 1-m length of the duct.
