The cover glass on a flat-plate solar collector has a low iron content, and its spectral transmissivity may be approximated by the following distribution. What is the total transmissivity of the cover glass to solar radiation? (Since it's a solar collector, assume the sun emits as a blackbody at 5800 K). 1.0 0.9 - λ1 = 0.4 με 0 0 1 A2 = 2.5 μm 2 3 λ, μm
