Wind Resistance Calculator

Formula

The formula to calculate the Wind Resistance is:

$WR = 0.5 \cdot Cd \cdot \rho \cdot A \cdot V^2$

Where:

$WR$ is the wind resistance (N).
$Cd$ is the drag coefficient (dimensionless).
$\rho$ is the air density (kg/m³).
$A$ is the cross-sectional area (m²).
$V$ is the velocity relative to the air (m/s).

What is Wind Resistance?

Wind resistance, also known as air resistance or drag, is the force exerted by air on an object moving through it. This force acts in the opposite direction to the object’s motion and increases with the square of the velocity. It is an important factor in various fields such as automotive design, aerospace engineering, and sports science.

Example

Let's say you have a drag coefficient (Cd) of 0.3, air density (ρ) of 1.225 kg/m³, cross-sectional area (A) of 2 m², and velocity (V) of 10 m/s. Using the formula:

$WR = 0.5 \cdot 0.3 \cdot 1.225 \cdot 2 \cdot 10^2 = 36.75 \, \text{N}$

So, the wind resistance (WR) would be 36.75 N.
