Emissivity of Small Body given Emitted Radiation and Temperature Solution

STEP 0: Pre-Calculation Summary

Formula Used

Emissivity = Emitted Radiation/([Stefan-BoltZ]*(Temperature^4))
ε = E_emit/([Stefan-BoltZ]*(T^4))
This formula uses 1 Constants, 3 Variables

Constants Used

[Stefan-BoltZ] - Stefan-Boltzmann Constant Value Taken As 5.670367E-8

Variables Used

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.
Emitted Radiation - (Measured in Watt per Square Meter) - 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.
Temperature - (Measured in Kelvin) - 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.

STEP 1: Convert Input(s) to Base Unit

Emitted Radiation: 2.811969 Watt per Square Meter --> 2.811969 Watt per Square Meter No Conversion Required

What is Kirchhoff law?

The total hemispherical emissivity of a surface at temperature T is equal to its total hemispherical absorptivity for radiation coming from a blackbody at the same temperature. This relation, which greatly simplifies the radiation analysis, was first developed by Gustav Kirchhoff in 1860 and is now called Kirchhoff’s law.
