Wind Pressure Formula:
From: | To: |
Definition: This calculator converts wind speed to dynamic pressure using air density and wind velocity.
Purpose: It helps engineers, architects, and meteorologists determine wind load for structural design and analysis.
The calculator uses the formula:
Where:
Explanation: The dynamic pressure increases with the square of wind speed and linearly with air density.
Details: Accurate wind pressure calculations are essential for designing buildings, bridges, and other structures to withstand wind loads.
Tips: Enter air density (default 1.225 kg/m³ for standard conditions) and wind speed in m/s. All values must be > 0.
Q1: What's the standard air density value?
A: At sea level and 15°C, air density is approximately 1.225 kg/m³.
Q2: How does altitude affect the calculation?
A: Air density decreases with altitude - use lower ρ values for high-altitude locations.
Q3: What units should I use for wind speed?
A: The calculator uses m/s. For km/h, divide by 3.6; for mph, divide by 2.237.
Q4: Is this dynamic or static pressure?
A: This calculates dynamic pressure (wind load). Static pressure is atmospheric pressure.
Q5: How accurate is this calculation?
A: It provides basic dynamic pressure. For structural design, consult building codes and consider additional factors.
