Kirchhoffs Law Radiative Transfer Calculator

Here is the Kirchhoff's law radiative transfer calculator to find source function using emission and absorption co-efficients. Radiative transfer is the emanation of electromagnetic radiation. It is affected by emission, absorption and scattering processes. Find the source function using the Kirchhoff's law of radiative transfer with this calculator. The law states that rate of thermal radiation discharged by the particle depends upon the radiation that passes through the nature of the surface.

Formula:

Sv = jv / αv Where, Sv = Source Function using Kirchhoff Law in Radiative Transfer jv = Specific Emission Coefficient αv =Absorption coefficient

Example

Find source function if the emission coefficient is 21 erg s-1cm-3Hz-1sr-1 and absorption coefficient is 31 cm-1.
Sv =21 / 31
Sv =0.67 erg s-1cm-2Hz-1sr-1.
