Radiative heat transfer is intended between the inner surfaces of two very large isothermal parallel metal plates. While the upper plate (designated as plate 1) is a black surface and is the warmer one being maintained at 727 °C the lower plate (plate 2) is a diffuse and gray surface with an emissivity of 0.7 and is kept at 227 °C. Assume that the surface are sufficiently large to form a two-surface enclosure and steady state conditions to exist. Stefan-Boltzmann constant is given as 5.67 x 10-8 W/m²-K4. (1) The irradiation (in kW/m²) for the plate (plate 1) is
