1. What is Resultant Force Due To External Water Pressure?

The Resultant Force due to External Water Pressure acting from base represents the hydrostatic forces caused by the pressure loading of a liquid acting on submerged surfaces. It is a crucial parameter in hydraulic engineering and structural design.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = \frac{1}{2} \times \Gamma_w \times H^2 \]

Where:

\( P \) — Resultant force due to external water (Pa)
\( \Gamma_w \) — Unit weight of water (N/m³)
\( H \) — Depth of water due to external force (m)

Explanation: This formula calculates the resultant hydrostatic force acting on a submerged surface, considering the unit weight of water and the depth of water.

3. Importance of Resultant Force Calculation

Details: Accurate calculation of resultant water force is essential for designing dams, retaining walls, hydraulic structures, and ensuring structural stability against water pressure.

4. Using the Calculator

Tips: Enter unit weight of water in N/m³ and depth of water in meters. All values must be positive and valid.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical unit weight of water?
A: The unit weight of water is typically 9807 N/m³ or 62.4 lb/ft³ at standard conditions.

Q2: How does water depth affect the resultant force?
A: The resultant force increases with the square of water depth, making depth a critical factor in force calculation.

Q3: Where is this calculation typically applied?
A: This calculation is used in dam design, retaining wall analysis, flood protection systems, and underwater structure design.

Q4: Are there limitations to this formula?
A: This formula assumes constant water density and uniform pressure distribution. It may need adjustments for varying conditions.

Q5: How accurate is this calculation for real-world applications?
A: While providing a good estimate, actual conditions may require additional factors such as water temperature variations, sediment content, and dynamic loading considerations.
