1. What is Wind Pressure Calculation?

Definition: This calculator determines the dynamic pressure exerted by wind based on air density and wind speed.

Purpose: It helps engineers, architects, and meteorologists assess wind loads on structures and objects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Wind pressure (Pascals)
• \( \rho \) — Air density (kg/m³)
• \( v \) — Wind speed (m/s)

Explanation: The wind pressure increases with the square of wind speed and linearly with air density.

3. Importance of Wind Pressure Calculation

Details: Accurate wind pressure calculation is crucial for structural design, wind load analysis, and safety assessments.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's a typical air density value?
A: At sea level and 15°C, air density is approximately 1.225 kg/m³. This decreases with altitude.

Q2: How do I convert wind speed from km/h to m/s?
A: Divide km/h by 3.6 (e.g., 36 km/h = 10 m/s).

Q3: Why does wind pressure increase with speed squared?
A: The kinetic energy of moving air increases quadratically with velocity.

Q4: When would I need to adjust air density?
A: For high-altitude locations or extreme temperatures where air density differs significantly from standard conditions.

Q5: How is this different from wind load?
A: Wind pressure is the basic calculation, while wind load considers additional factors like shape coefficients and structure size.
