Calculate Drag Force Percent (DFP)



Formula

The formula to calculate the Drag Force Percent (DFP) is:

\[ DFP = \left( \frac{DF_{reduced}}{DF_{original}} \right) \times 100 \]

What is Drag Force Percent?

Drag force percent is a measure of the effectiveness of drag reduction techniques. It compares the drag force experienced by an object with and without drag reduction measures. This percentage helps in understanding how much the drag force has been reduced due to the implementation of these techniques. A lower drag force percent indicates a more effective drag reduction.

Example

Let's say the drag force with reduction (DFreduced) is 50 N, and the drag force without reduction (DForiginal) is 100 N. Using the formula:

\[ DFP = \left( \frac{50}{100} \right) \times 100 = 50 \% \]

So, the drag force percent (DFP) is 50%.

Calculation of Drag Force

Formula: \( F_d = \frac{1}{2} \rho v^2 C_d A \)

Example: \( F_d = \frac{1}{2} \times 1.225 \times 30^2 \times 0.47 \times 2 \)

Calculate the Ratio of the Drag Force

Formula: \( \text{Ratio} = \frac{F_{d1}}{F_{d2}} \)

Example: \( \text{Ratio} = \frac{500}{250} \)

How to Find Average Drag Force

Formula: \( \text{Average Drag Force} = \frac{\sum F_d}{n} \)

Example: \( \text{Average Drag Force} = \frac{1000}{5} \)

Total Drag Force Formula

Formula: \( \text{Total Drag Force} = \sum F_d \)

Example: \( \text{Total Drag Force} = 200 + 300 + 500 \)
