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 = Eemit/([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 - 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.
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 = Eemit/([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

Emissivity of Small Body given Emitted Radiation and Temperature Formula

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