7 A rectangular surface of 4 m2 was exposed to solar radiation of 1400 W/m2. The temperature of the surface was maintained at 500K. The spectral absorptivity of the surface is given as 0 for 0> λ (μm) < 0.5, 0.8 for 0.5> λ (μm)< 1, 0 for 1< λ (μm) < 2, and 0.9 for λ (μm)>2. Assuming the surface is diffuse and the sun temperature is 5800K, calculate the absorbed irradiation, radiosity, and net radiation heat transfer from the surface.
