The formula to calculate the Heat Exchange by Radiation is:
\[ q = \varepsilon \cdot A \cdot \text{Stefan-BoltZ} \cdot SF \cdot (T_1^4 - T_2^4) \]
Where:
Heat Transfer is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second).
Let's assume the following values:
Using the formula:
\[ q = 0.95 \cdot 50 \cdot 5.670367E-8 \cdot 4.87 \cdot (101^4 - 151^4) \]
Evaluating:
\[ q = -5454.36936101831 \text{ W} \]
The Heat Transfer is -5454.36936101831 W.
