Wind Pressure and Force Calculator

Formulas

The formula to calculate the Wind Pressure (WP) is:

$\text{WP} = \frac{1}{2} \cdot \text{p} \cdot \text{V}^2$

Where:

$\text{WP}$ is the wind pressure (Pa)
$\text{p}$ is the air density (kg/m³)
$\text{V}$ is the air velocity (m/s)

The formula to calculate the Wind Force (F) is:

$\text{F} = \text{WP} \cdot \text{A} = \frac{1}{2} \cdot \text{p} \cdot \text{V}^2 \cdot \text{A}$

Where:

$\text{F}$ is the wind force (N)
$\text{A}$ is the surface area (m²)

Wind Pressure Definition

Wind pressure is defined as the dynamic force per unit area that is acting on an object that is being affected by the movement of air. It is an important factor in determining the wind load on structures and is critical for engineering and safety calculations.

Example Calculation

Let's assume the following values:

Air Density (p) = 1.225 kg/m³
Air Velocity (V) = 10 m/s
Surface Area (A) = 2 m²

Using the formulas:

Wind Pressure (WP):

$\text{WP} = \frac{1}{2} \cdot 1.225 \cdot (10)^2 = \frac{1}{2} \cdot 1.225 \cdot 100 = 61.25 \text{ Pa}$

Wind Force (F):

$\text{F} = 61.25 \cdot 2 = 122.5 \text{ N}$

The Wind Pressure (WP) is 61.25 Pa, and the Wind Force (F) is 122.5 N.
