The spectral, hemispherical absorptivity of an opaque
Chapter , Problem 12.57(choose chapter or problem)
The spectral, hemispherical absorptivity of an opaque surface and the spectral distribution of radiation incident on the surface are as shown. What is the total, hemispherical absorptivity of the surface? If it is assumed that and that the surface is at 1000 K, what is its total, hemispherical emissivity? What is the net radiant heat flux to the surface? 1
