Lift force ( \(L\) ) for an body moving through a fluid (gas or liquid), is the force exerted perpendicular to the direction of travel.

Lift Force formula

\(\large{ L = \frac {1} {2} C_l \rho v^2 A }\)         

\(\large{ L = \frac  { C_l \rho v^2 A } { 2 } }\)         

Where:

\(\large{ L }\) = lift force

\(\large{ A }\) = area

\(\large{ C_l }\) = lift coefficient

\(\large{ \rho }\)  (Greek symbol rho) = density

\(\large{ v }\) = velocity

Solve for:

\(\large{ C_l = \frac {2 L} {\rho v^2 A} }\)

\(\large{ \rho = \frac {2 L} { C_l v^2 A} }\)

\(\large{ v =   \sqrt { \frac {2 L} { C_l \rho A}   }   }\)

\(\large{ A = \frac {2 L} { C_l \rho v^2}   }\)
