1. What is a Wind Speed To Force Calculator?

Definition: This calculator estimates the force exerted by wind based on air density, surface area, and wind speed.

Purpose: It helps engineers, architects, and designers determine wind loads for structural calculations and safety assessments.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F \) — Wind force (Newtons)
• \( \rho \) — Air density (kg/m³)
• \( A \) — Surface area (m²)
• \( V \) — Wind speed (m/s)

Explanation: The force increases with the square of wind speed, meaning small speed increases create much larger forces.

3. Importance of Wind Force Calculation

Details: Accurate wind force estimation is crucial for structural integrity, safety standards compliance, and material selection in construction.

4. Using the Calculator

Tips: Enter air density (default 1.225 kg/m³ at sea level), surface area, and wind speed. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the standard air density value?
A: At sea level and 15°C, it's approximately 1.225 kg/m³. Decreases with altitude.

Q2: How does wind speed affect the force?
A: Force increases with the square of speed - double the speed means 4x the force.

Q3: What surface area should I use?
A: Use the projected area perpendicular to wind direction. For buildings, use height × width.

Q4: How to convert wind speed from km/h to m/s?
A: Divide km/h by 3.6 (e.g., 100 km/h = 27.78 m/s).

Q5: What's a typical wind force on a house?
A: A 20 m/s wind on a 100 m² wall would create about 24,500 N (2.5 metric tons) of force.
