Lift Coefficient

Lift coefficient ( \(C_l\) ) (dimensionless number) is the lift generated by a lifting body to the fluid density around the body.

Lift Coefficient formula

\(C_l =  \frac {L} { \frac {1}{2}  \rho v^2 A}  = \frac {2L} { \rho v^2 A} =  \frac {L} { Q A}\)          \( lift \; coefficient  \;=\;  \frac { lift \; force} { dynamic \; pressure \;\;x\;\;  area}\)

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

Where:

\(C_l\) = lift coefficient

\(L\) = lift force

\(v\) = velocity

\(\rho\) = fluid density

\(A\) = area

\(Q\) = dynamic pressure
