Calculate Cd Gain (Cd_{gain})









Formula

The formula to calculate the Cd Gain (Cd_{gain}) is:

\[ Cd_{gain} = \frac{2 \cdot F_d}{\rho \cdot A \cdot v^2} - Cd_{initial} \]

Where:

Definition

Example

Let's say the drag force (F_d) is 100 N, the air density (ρ) is 1.225 kg/m³, the area (A) is 2 m², the velocity (v) is 30 m/s, and the initial drag coefficient (Cd_{initial}) is 0.3. Using the formula:

\[ Cd_{gain} = \frac{2 \cdot 100}{1.225 \cdot 2 \cdot 30^2} - 0.3 \approx -0.41 \]

So, the Cd gain is approximately -0.41.
