Consider a plate (it is a black body) at 400 K which is covered by a glass layer. If the rate of solar radiation striking the glass layer is 1 kW/m, determine (a) the solar radiation flux absorbed by the plate, and (b) the transmissivity of the glass layer for radiation emitted by the plate. For the glass layer: T = 0 for 1 < 0.4 m T20.9 for 0.44 p m T30.1 for 4 m
