Lift Force Calculator

Calculate lift force from fluid density, lift coefficient, reference area and speed, with dynamic pressure.

CL is not universal; it depends on geometry, angle of attack, Reynolds number and flow state.

How to use

The standard quadratic lift relation gives lift when fluid density, speed, reference area and lift coefficient are known.

  1. Enter fluid density.
  2. Enter CL and reference area.
  3. Enter relative speed.
  4. Review lift and dynamic pressure.

How it is calculated

L=½ρCLAv²

Example

At ρ=1.225 kg/m³, CL=1, A=16 m² and v=50 m/s, lift is about 24.5 kN.

Important notes

The calculator does not infer CL from geometry; use a coefficient appropriate to the actual configuration.

Frequently asked questions

Is lift always upward?

Direction depends on coefficient sign and geometry/flow orientation.

What if speed doubles?

Lift quadruples if all other inputs stay fixed.

Can this be used in water?

Yes when the lift model and CL are appropriate.
