Question: Two parallel plates 1 m by 2 m are spaced 1 m apart. Plate 1 is at 1000C with an emissivity of 0.2 and Plate

Two parallel plates 1 m by 2 m are spaced 1 m apart. Plate 1 is at 1000C with an emissivity of 0.2 and Plate 2 is at 500C with an emissivity of 0.5. The plates are in a very large room where the walls are maintained at 27C. Consider only the plates surfaces that face each other. Determine: Heat lost by Plate 1 in kW; Heat gained by the Room in kW; and Plate 2 heat transfer in kW and its direction (loss or gain)
