Ah ha. My TT is 8' wide and 10' tall but it isn't 80 sq. ft. After all it's on wheels.
OK, 8 ft wide and 8 ft tall? 64 sq ft?
Nope, it is kinda streamlined.
The equation for wind resistance is (1/2)*(density of air)*(frontal area)*(drag coefficient)*(velocity)^2
The drag coefficient is dependent on the shape of the object. A wedge would have a smaller drag coefficient than a box.
I'm no fool an I didn't just jump into this.
Adjusted frontal area, backed out from wind resistance is 43 sq ft.
