int-baking consi long, triangular iS at 1200 K and another surface is insulated. Painted panels, which are maintained at 500 K, occupy the third surface. The triangle is of width 1 m on a side, and heated and insulated surfaces have an emissivity of 0.8. The emissivity of panels is 0. 4. During steady-state operation, at what rate must energy be supplied to heated side per unit length of duct to maintain its temperature at 1200 K? What is the temperature of the insulated surface?
