A solar collector consists of a long duct through which air is blown; its cross section forms an equilateral triangle 1 m on a side. One side consists of a glass cover of emissivity = 0.9, while the other two sides are absorber plates with 2 = ₁ = 1.0. E₁, T₁ Glass cover ez, T₂- €₂. T₂ -Absorber plates During operation the surface temperatures are known to be T₁ = 25°C, T₂ = 45°C, and T₁ = 80°C. What is the net rate at which radiation is transferred to the cover due to exchange with the absorber plates, in W/m?
