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 thermal radiation compared to a perfect black body, influencing heat transfer in thermal systems.
Emitted Radiation - (Measured in Watt per Square Meter) - Emitted Radiation is the radiation emitted by a body.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.

STEP 1: Convert Input(s) to Base Unit

Emitted Radiation: 2.8 Watt per Square Meter --> 2.8 Watt per Square Meter No Conversion Required
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ε = E_emit/([Stefan-BoltZ]*(T^4)) --> 2.8/([Stefan-BoltZ]*(85^4))

Evaluating ... ...

ε = 0.945956487674259

STEP 3: Convert Result to Output's Unit

0.945956487674259 --> No Conversion Required

FINAL ANSWER

0.945956487674259 ≈ 0.945956 <-- Emissivity

Temperature of Small Body using Absorptivity and Absorbed Radiation

Go Temperature = (Absorbed Radiation/([Stefan-BoltZ]*Absorptivity))^0.25

Temperature of Small Body given Emissivity and Emitted Radiation

Go Temperature = (Emitted Radiation/(Emissivity*[Stefan-BoltZ]))^0.25

Radiation Absorbed by Small Body Per Unit of its Surface Area

Go Absorbed Radiation = Absorptivity*[Stefan-BoltZ]*(Temperature^4)

Radiation emitted by small body

Go Emitted Radiation = Emissivity*[Stefan-BoltZ]*(Temperature^4)

Emissivity of Small Body given Emitted Radiation and Temperature Formula

Emissivity = Emitted Radiation/([Stefan-BoltZ]*(Temperature^4))
ε = E_emit/([Stefan-BoltZ]*(T^4))

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.
