Lift Coefficient

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Lift coefficient is a dimensionless number, the lift generated by a lifting body to the fluid density around the body.

formula

\(C_L =  \frac {L} { \frac {1}{2}  \rho v^2 A}  = \frac {2L} { \rho v^2 A} =  \frac {L} { Q A}\) 

Where:

\(C_L\) = lift coefficient

\(L\) = lift force

\(v\) = velocity

\(\rho\) = fluid density

\(A\) = area

\(Q\) = dynamic pressure
