The variation of the spectral transmissivity of a 0.6-cm-thick glass window is as given in Fig. P12–59. Determine the average transmissivity of this window for solar radiation (T ≈ 5800K) and radiation coming. from surfaces at room temperature (T ≈ 300 K). Also, determine the amount of solar radiation transmitted through the window for incident solar radiation of 650 W/m2.

Answers: 0.870, 0.00016. 566 W/m2
