Electrically Powered Ultralight Aircraft
wrote)
The coefficient of drag for motorcycles is usually pretty bad unless they are faired, and it still ain't great. The power required to overcome drag is 1/2(p*v^3*A*C) p is the densitity of the fluid v is the airspeed A is the area C is the coefficient of drag 80-ft length of the semi (vs.) 8-ft length of the motorcycle Does this play (much) of a role here? Is that role expressed (adequately/sufficiently) in the above formula, through "C" ...drag?
