Acylindrical wall has a temperature of 800 c on the inside and is exposed to air and room surfaces at 20 on the outside. if the wall has an inside diameter of 0.5 m, thickness of 10 cm, height of 0.5 m, and thermal conductivity of 0.5 w/(m. k), and th exposed outside surface has a convection coefficient of is w/(m2·k), (a) how much heat is transmitted through the wall (in watts), and (b) what is the temperature of the exposed outside of the wall?
