Drag Force

Written by Jerry Ratzlaff on . Posted in Fluid Mechanics

Drag force or drag for any body moving through a fluid (gas or liquid), is the force exerted perpendicular and in opposition to the direction of travel.

formula

\( F_D = \frac {1} {2}  \rho v^2  C_D    A \)

Where:

\(F_D\) = drag force

\(\rho\) = density

\(v\) = velocity

\(C_D\) = drag coefficient

\(A\) = area
