Radiation emitted by small body Solution

STEP 0: Pre-Calculation Summary
Formula Used
Emitted Radiation = Emissivity*[Stefan-BoltZ]*(Temperature^4)
Eemit = ε*[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
Emitted Radiation - (Measured in Watt per Square Meter) - Emitted Radiation is the radiation emitted by a body.
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.
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
Emissivity: 0.95 --> No Conversion Required
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Eemit = ε*[Stefan-BoltZ]*(T^4) --> 0.95*[Stefan-BoltZ]*(85^4)
Evaluating ... ...
Eemit = 2.81196866310406
STEP 3: Convert Result to Output's Unit
2.81196866310406 Watt per Square Meter --> No Conversion Required
FINAL ANSWER
2.81196866310406 2.811969 Watt per Square Meter <-- Emitted Radiation

6 Kirchhoff's Law Calculators

Temperature of Small Body using Absorptivity and Absorbed Radiation
Go Temperature = (Absorbed Radiation/([Stefan-BoltZ]*Absorptivity))^0.25
Absorptivity of Small Body using Absorbed Radiation and Temperature
Go Absorptivity = Absorbed Radiation/([Stefan-BoltZ]*(Temperature^4))
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)
Emissivity of Small Body given Emitted Radiation and Temperature
Go Emissivity = Emitted Radiation/([Stefan-BoltZ]*(Temperature^4))
Radiation emitted by small body
Go Emitted Radiation = Emissivity*[Stefan-BoltZ]*(Temperature^4)

Radiation emitted by small body Formula

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