Calculate Heat Exchange by Radiation











Formula

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:

Definition

Heat Transfer is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second).

Example Calculation

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.
