Lift Coefficient

The lift coefficient is a dimensionless coefficient that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area.

The lift coefficient equals twice the lift divided by the planform area, the true airspeed squared and the mass density of the air.

Formula

QuantityVariable[Subscript["C", "L"], "LiftCoefficient"] == (2*QuantityVariable["L", "Force"])/(QuantityVariable["A", "Area"]*QuantityVariable["v", "Speed"]^2*QuantityVariable["ρ", "MassDensity"])
