## Q. 12.4

Use the emission approximation to find the energy flux emerging from an isothermal gas layer at T_g with an integrated mean absorption coefficient weighted by the blackbody spectrum at T_g (the “Planck mean” in Section 12.6.1) of κ_P = 0.010 cm^{−1} and thickness D = 1.5 cm, if the layer is bounded by transparent nonradiating walls and cold surroundings (Figure 12.1a).
