Drag Force Calculator
Calculate the aerodynamic drag force on an object moving through fluid
Typical values: Sphere~0.47, Cylinder~1.2, Car~0.3-0.5, Airplane~0.02-0.04
Air at sea level: 1.225 kg/m³, Water: 1000 kg/m³
Drag Force Formula
Fd = (1/2) * Cd * rho * v² * A
Where:
- Cd = drag coefficient (dimensionless)
- rho = fluid density (kg/m³)
- v = velocity (m/s)
- A = reference area (m²)
