Results

Lift Coefficient (C_L)

0.1633

Dynamic Pressure (q)

1531.25 Pa

Formula

C_L = L / (0.5 × ρ × v² × A)

C_L is dimensionless. Dynamic pressure q = 0.5 ρ v².

How to use

Enter lift force (N), air density (kg/m³), velocity (m/s) and wing area (m²). The calculator returns C_L and q.

Example

Lift 5000 N, ρ=1.225 kg/m³, v=50 m/s, A=20 m² → C_L ≈ 0.45 (example).

FAQs

Q: Units? A: Use SI units. Q: Is C_L constant? A: It depends on angle of attack and flow.
