Drag Force on a Streamlined Body

  • #1

Main Question or Discussion Point

Hi,

I know that the drag force on an object: Fd= 1/2 . ρ . v^2 . Cd . A

where A is the reference area.

But in the case of a streamlined body, I don't know what will be taken as the reference area. Should it be the largest cross-sectional area of the body?

Oh sorry, in this case I'm talking about drag force caused by air resistance

Yes, the cross section area as seen from the direction of the wind
