The image above represents energy flux. To calculate energy flux, two essential parameters are needed: Stefan-Boltzmann’s Constant (σ) and Absolute Temperature (T).
The formula for calculating energy flux:
eL = σT4
Where:
eL = Energy Flux
σ = Stefan-Boltzmann’s Constant
T = Absolute Temperature
Let’s solve an example;
Find the energy flux when the stefan-boltzmann’s constant is 5.67e-8 and the absolute temperature is 20.
This implies that;
σ = Stefan-Boltzmann’s Constant = 5.67e-8
T = Absolute Temperature = 20
eL = σT4
eL = (5.67e-8)(20)4
That is, eL = (5.67e-8)(160000)
eL = 0.009072
Therefore, the energy flux is 0.009072 W/m².
