Lift Force

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

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

formula

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

Where:

\(L\) = lift force

\(C_L\) = lift coefficient

\(v\) = velocity

\(\rho\) = density

\(A\) = area

Solve for:

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

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

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

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