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

\(L = \frac {1} {2} C_l \rho v^2 A \)          \(lift \; force  \;=\;    \frac {1} {2} \;  \left( \;  lift \; coefficient   \;\;x\;\;  density  \;\;x\;\;   velocity^2  \;\;x\;\;  area  \; \right) \)

\(L = \frac  { C_l \rho v^2 A } { 2 } \)          \(lift \; force  \;=\;    \frac  { lift \; coefficient   \;\;x\;\;  density  \;\;x\;\;   velocity^2  \;\;x\;\;  area } { 2 } \)

Where:

\(L\) = lift force

\(A\) = area

\(C_l\) = lift coefficient

\(\rho\) (Greek symbol rho) = density

\(v\) = velocity

Solve for:

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

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

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

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