Q6. Two large parallel plates are maintained at 300 and 500C,

Q6. Two large parallel plates are maintained at 300 and 500C, respectively, and have surface emissivities of 0.8 . A polished-aluminum radiation shield (emissivity=0.1) is placed equidistant between the two plates. 1- Sketch the radiation network for plates- shield arrangement. 2- Calculate the radiant heat transfer through the plate shield arrangement per m2 of surf area
