The formula to calculate the Center of Pressure is:
\[ h? = D + \frac{I}{A_{\text{wet}} \cdot D} \]
The Center of Pressure is the point where the total sum of a pressure field acts on a body, causing a force to act through that point. Depth of Centroid is the depth below the free surface. Moment of Inertia is the measure of an object's resistance to changes to its rotation. Wet Surface Area is the surface area of the horizontal wetted plane.
Let's assume the following values:
Using the formula:
\[ h? = 0.45 + \frac{3.56}{0.56 \cdot 0.45} = 14.5769841269841 \text{ m} \]
| Depth of Centroid (D) | Moment of Inertia (I) | Wet Surface Area (Awet) | Center of Pressure (h?) |
|---|---|---|---|
| 0.4 m | 3.56 kg·m² | 0.56 m² | 16.292857142857 m |
| 0.45 m | 3.56 kg·m² | 0.56 m² | 14.576984126984 m |
| 0.5 m | 3.56 kg·m² | 0.56 m² | 13.214285714286 m |
