1. What is Wind Force Per Square Foot?

Definition: This calculator estimates the wind pressure exerted per square foot based on wind speed.

Purpose: It helps engineers, architects, and construction professionals determine wind loads for structural design.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Wind pressure (pounds per square foot, psf)
• \( v \) — Wind velocity (miles per hour, mph)

Explanation: The formula calculates the dynamic pressure exerted by wind at a given velocity.

3. Importance of Wind Force Calculation

Details: Proper wind load estimation ensures structural integrity, safety, and code compliance for buildings and other structures.

4. Using the Calculator

Tips: Enter the wind speed in miles per hour. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where does the 0.00256 constant come from?
A: It's derived from the density of air and unit conversion factors for the equation.

Q2: Is this the same as design wind pressure?
A: This gives basic wind pressure. Design wind loads consider additional factors like exposure, height, and building shape.

Q3: What's a typical wind speed for calculations?
A: Design wind speeds vary by location but often range from 90-150 mph for most areas.

Q4: Does this account for gusts?
A: No, this is for sustained wind speeds. Gust factors would be applied separately.

Q5: How does wind pressure relate to building codes?
A: Building codes specify minimum design wind loads based on this basic calculation with additional safety factors.
