Chapter 12 Radiation Heat Transfer Also Δα = Δε , but the emissivity correction factor is to be evaluated from Fig. 12-38 at T = T s = 600 K instead of T g = 1500 K. There is no chart for 600 K in the figure, but we can read Δε values at 400 K and 800 K, and take their average. At P w /( P w + P c ) = 0.6 and P c L + P w L = 0.07 we read Δε = 0.0. Then the absorptivity of the combustion gases becomes 0.097 0 . 0 041 . 0 056 . 0 = + = α Δ α + α = α w c g
