Constants

Emitted Radiation

The Emitted Radiation is the energy released by a surface in the form of electromagnetic waves, influenced by its temperature and material properties according to Kirchhoff's Law.

Symbol: E_emit

Measurement: Heat Flux DensityUnit: W/m²

Note: Value should be greater than 0.

Formulas to find Emitted Radiation

Emissivity

The Emissivity is a measure of a material's ability to emit energy as thermal radiation, reflecting its efficiency in radiating heat compared to a perfect black body.

Symbol: ε

Measurement: NAUnit: Unitless

Note: Value should be between 0 to 1.

Formulas to find Emissivity

Temperature

The Temperature is a measure of the thermal energy of a system, indicating how hot or cold it is, and plays a crucial role in heat transfer processes.

Symbol: T

Measurement: TemperatureUnit: K

Note: Value can be positive or negative.

Formulas to find Temperature

Stefan-Boltzmann Constant

Stefan-Boltzmann Constant relates the total energy radiated by a perfect black body to its temperature and is fundamental in understanding blackbody radiation and astrophysics.

Symbol: [Stefan-BoltZ]

Value: 5.670367E-8

Other formulas in Kirchhoff's Law category

Go Temperature of Small Body given Emissivity and Emitted Radiation

T = {(\frac{E emit}{ε \cdot [Stefan-BoltZ]})}^{0.25}

Go Temperature of Small Body using Absorptivity and Absorbed Radiation

T = {(\frac{G abs}{[Stefan-BoltZ] \cdot α})}^{0.25}

Go Radiation Absorbed by Small Body Per Unit of its Surface Area

G abs = α \cdot [Stefan-BoltZ] \cdot (T^{4})

Go Emissivity of Small Body given Emitted Radiation and Temperature

ε = \frac{E emit}{[Stefan-BoltZ] \cdot (T^{4})}
