one needs to add an area and density to that equation to get drag force
Drag = Cd x rho/2 x Area x Velocity^2
the area is frontal cross section area for automobiles, its the wing planform for airplanes ;
rho is .002377 for sea level, .002 for normal warm days.
density is slugs per cubic foot, velocity in feet per second, area in square feet.
Can you tell I are an inguneer
Take a picture from the front with a big yardstick to get the cross sectional area. I'll try to do that this weekend and post the number here.
