A chamber for heat curing large aluminum sheets lacquered black on both sides operates by passing the sheets vertically between two steel plates 150 mm apart. One of the plates is at 300°C, and the other exposed to the atmosphere, is at 25°C. i) What is the temperature of the lacquered sheet? and ii) What is the heat transferred between the wall when equilibrium has been reached? Neglect the convection effects and the emissivity of lacquered sheet is 1.
