The formula to calculate the Real Surface Radiant Surface Emittance is:
\[ e = \epsilon \cdot [\text{Stefan-BoltZ}] \cdot T_w^4 \]
Where:
Real surface radiant surface emittance is the emittance by normal objects (non-black body).
Let's assume the following values:
Using the formula:
\[ e = 0.95 \cdot 5.670367E-8 \cdot 305^4 \]
Evaluating:
\[ e = 466.159061868529 \text{ W/m²} \]
The Real Surface Radiant Surface Emittance is 466.159061868529 W/m².
