The spectral transmissivity of a glass cover used in a solar collector is given as

Solar radiation is incident at a rate of 950 W/m2, and the absorber plate, which can be considered to be black, is maintained at 340 K by the cooling water. Determine (a) the solar flux incident on the absorber plate, (b) the transmissivity of the glass cover for radiation emitted by the absorber plate, and (c) the rate of heat transfer to the cooling water if the glass cover temperature is also 340 K.
