Theory & Logic
Theoretical Background
Physics describes the fundamental mechanism of the universe. The Drag Force Equation is an essential tool for understanding Drag Force Equation in quantitative terms. Calculate Fd = 0.5 * ρ * v² * Cd * A.
Mathematical Formulation
The relationship between the variables is governed by the following equation:
Variable Legend
| Symbol | Parameter | Unit |
|---|---|---|
| rho | Density | kg/m³ |
| v | Velocity | m/s |
| cd | Drag Coeff | |
| a | Ref Area | m² |
Practical Calculation Example
Problem
Calculating the result when:
- Density = 25 kg/m³
- Velocity = 40 m/s
- Drag Coeff = 95
- Ref Area = 25 m²
Solution
Substituting into Eq 1.1:
Result = 0.5 × 25 × 40 × 40 × 95 × 25
