The formula to calculate the One Dimensional Heat Flux is:
\[ q = -\frac{k_o}{t} \cdot (T_{w2} - T_{w1}) \]
Where:
Heat Flux is the heat transfer rate per unit area normal to the direction of heat flow. It is denoted by the letter "q".
Let's assume the following values:
Using the formula:
\[ q = -\frac{10.18}{0.13} \cdot (299 - 300) \]
Evaluating:
\[ q = 78.3076923076923 \text{ W/m²} \]
The Heat Flux is 78.3076923076923 W/m².
