This drag coefficient calculator helps you determine the resistance an object experiences as it moves through a fluid, such as air or water.
Drag Coefficient Calculator
This calculator allows you to find the drag coefficient based on the drag force, velocity of the object through a fluid, the reference area, and the fluid density.
How to Use the Calculator
Enter the drag force in newtons (N), the velocity in meters per second (m/s), the reference area in square meters (m²), and the fluid density in kilograms per cubic meter (kg/m³) into their corresponding fields. Click ‘Calculate’ to get the result.
How It Calculates the Results
The drag coefficient (Cd) is calculated using the formula:
[Cd = frac{2 times F_d}{rho times v^2 times A}]
- (F_d) = Drag Force
- (rho) = Fluid Density
- (v) = Velocity
- (A) = Reference Area
The result is dimensionless and provides a measure of the drag or resistance of an object in a fluid environment.
Limitations
This calculator assumes a constant velocity and a single-phase, incompressible, and non-turbulent fluid. If your situation doesn’t fit these assumptions, the results may be inaccurate.
