Hydrostatic Pressure + Resultant (Vertical Wall)

Computes pressure diagram, resultant force, center of pressure and base moment for a vertical rectangular wall. Choose a “Standard/Profile” for unit weight γ and apply an optional factor (per your code combination).

Standard / Profile

Codes/standards typically use unit weight of water close to 9.81 kN/m³; some engineering practice uses 10 kN/m³ for quick checks.

Unit weight γ (kN/m³)

Load factor (optional)

Keep 1.0 for service pressure; apply your code load factor if needed.

Water depth h (m)

Wall width b (m) (into page)

Use b = 1.0 for per-meter design values.

Load sample

Assumptions: vertical wall, free surface at top of water, hydrostatic pressure varies linearly: p(z)=γ·z.
