Radiation Heat Transfer Properties
Surface emissivity, ε, which is the emission of the surface compared to an ideal blackbody, E/Eb.
Where σ is the Stefan-Boltzmann constant, (5.670 × 10−8 W/m2-K4), T is surface temperature and the subscript λ refers to wavelength.
Incident radiation balance: α + τ + ρ = 1
