Absorptivity of Small Body using Absorbed Radiation and Temperature Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absorptivity = Absorbed Radiation/([Stefan-BoltZ]*(Temperature^4))
α = G_abs/([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

Absorptivity - Absorptivity is the fraction of incident radiation flux absorbed by the body.
Absorbed Radiation - (Measured in Watt per Square Meter) - Absorbed radiation is the amount of radiation energy absorbed by the body per its unit surface area.
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

Absorbed Radiation: 260 Watt per Square Meter --> 260 Watt per Square Meter No Conversion Required
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = G_abs/([Stefan-BoltZ]*(T^4)) --> 260/([Stefan-BoltZ]*(85^4))

Evaluating ... ...

α = 87.8388167126097

STEP 3: Convert Result to Output's Unit

87.8388167126097 --> No Conversion Required

FINAL ANSWER

87.8388167126097 ≈ 87.83882 <-- Absorptivity

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)

Absorptivity of Small Body using Absorbed Radiation and Temperature Formula

Absorptivity = Absorbed Radiation/([Stefan-BoltZ]*(Temperature^4))
α = G_abs/([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.
