Calculation of Pressure Forces on Submerged Rectangular Plates (continued)

Case 4: Calculation of Pressure Forces on a submerged Slanted plate (continued)

Magnitude and Location of Pressure Forces, F₁ and F₂.

The magnitudes of the pressure forces are F₁ = γ d ( 2hw ) and F₂ = γ h cosα ( 2hw ).

The location of each individual pressure force acts at the “centroid” of its pressure prism.

For F₁ the centroid is at the center of the rectangle. For F₂ the centroid is at the center of

the triangle.
