Question 5 (8 marks) Note: Parts (5.1) and (5.2) are not related and each carries 4 marks. (5.1) The spectral transmissivity of plain and tinted glass can be approximated as follows: Plain glass: -0.9 for 0.31 ≤ ≤ 2.59 μm Tinted glass: t=0.9 for 0.50 às 1.38 µm Outside the specified wavelength ranges, the spectral transmissivity is zero for both glasses. Calculate the total transmissivity of each glass and % reduction in solar energy transmitted using the tinted glass. Assume that the spectral distribution of solar irradiation is proportional to that of blackbody emission at 5800 K.
