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

**The formula for calculating energy flux:**

e_{L} = ÏƒT^{4}

Where:

e_{L} = 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

e_{L} = ÏƒT^{4}

e_{L} = (5.67e-8)(20)^{4}

That is, e_{L} = (5.67e-8)(160000)

e_{L} = 0.009072

Therefore, the **energy flux **is **0.009072 W/mÂ².**
