The formula to calculate Heat Flux is:
\[ q = ht \cdot (T_w - T_f) \]
Where:
Heat Flux is the heat transfer rate per unit area normal to the direction of heat flow.
Let's assume the following values:
Using the formula:
\[ q = 2.59 \cdot (305 - 275) \]
Evaluating:
\[ q = 77.7 \text{ W/m²} \]
The Heat Flux is 77.7 W/m².
| Heat Transfer Coefficient (ht) | Surface Temperature (Tw) | Temperature of Characteristic Fluid (Tf) | Heat Flux (q, W/m²) |
|---|---|---|---|
| 2 | 305 | 275 | 60.000 |
| 3 | 305 | 275 | 90.000 |
| 4 | 305 | 275 | 120.000 |
| 5 | 305 | 275 | 150.000 |
