Question: problem 5 the solar radiation incident on the outside surface...

Question details

Problem 5 The solar radiation incident on the outside surface of an aluminum shading device is 1300 W/m. Aluminum absorbs 10% of the incident solar energy, and dissipates it by convection from the back surface and by combined convection and radiation from the outside surface. The convection heat transfer coefficient is 10 W/m2 K for both surfaces, and the ambient/surrounding temperature can be taken 20 C for both convection and radiation. Assuming that the aluminum shade has a uniform temperature, determine the temperature of the aluminum shading device if it is 1 Polished. and 2 Oxidized
