Calculate Black-Body Radiant Emittance



Formula

The formula to calculate the Black-Body Radiant Emittance is:

\[ e_b = \sigma \cdot T^4 \]

Where:

Definition

Black-Body Radiant Emittance is the radiant flux emitted by a surface per unit area.

Example Calculation

Let's assume the following value:

Using the formula:

\[ e_b = 5.670367E-8 \cdot 85^4 \]

Evaluating:

\[ e_b = 2.95996701379375 \text{ W/m²} \]

The Black-Body Radiant Emittance is 2.95996701379375 W/m².
