Also, a quick re-read of my first post, I believe I might should have prefaced my calculations.

Coefficient of Drag [no units] = Drag [force] / (.5 x density of air [mass/area] x velocity^2 [distance/time] x frontal area [area])

EFPD [area] = Drag [force] / (.5 x density of air [mass/area] x velocity^2 [distance/time])
