Note: Value should be greater than 0.

Formulas to find Radiosity

Emissivity

Emissivity is the ability of an object to emit infrared energy. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody). Most organic or oxidized surfaces have emissivity close to 0.95.

Symbol: ε

Measurement: NAUnit: Unitless

Note: Value should be between 0 to 1.

Formulas to find Emissivity

Emissive Power of Blackbody

Emissive Power of Blackbody is the energy of thermal radiation emitted in all directions per unit time from each unit area of a surface of blackbody at any given temperature.

Symbol: E_b

Measurement: Heat Flux DensityUnit: W/m²

Note: Value should be greater than 0.

Formulas to find Emissive Power of Blackbody

Reflectivity

Reflectivity is the fraction of incident radiation flux reflected by the body.
