The angle is measured from the horizontal free surface, and the top-edge depth is a vertical distance.
- Resultant force
- 206.0 kN
- Centroid vertical depth,
- 3.500 m
- Center-of-pressure vertical depth,
- 3.714 m
- Center of pressure from top edge
- 1.714 m
This model assumes a static, constant-density liquid and uniform pressure at the free surface. It reports both the distance along the plane and the vertical depth, which must not be interchanged in center-of-pressure calculations.
