# How to Calculate and Solve for Energy Flux | Energy Transport

The image above represents energy flux. To calculate energy flux, two essential parameters are needed: Stefan-Boltzmann’sÂ Constant (Ïƒ) and Absolute Temperature (T).

### The formula for calculating energy flux:

eL = ÏƒT4

Where:

eL = Energy Flux
Ïƒ = 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;

Ïƒ = Stefan-Boltzmann’s Constant = 5.67e-8
T = Absolute Temperature = 20

eL = ÏƒT4
eL = (5.67e-8)(20)4
That is, eL = (5.67e-8)(160000)
eL = 0.009072

Therefore, the energy flux is 0.009072 W/mÂ².
