An airplane of a certain density and shape flies at a constant speed. To do so, it must fly with a certain velocity v0. If the size of the airplane is scaled up in length, width, and height by a factor of two, it can only fly above a new velocity v1. What is v1/v0?
Details and assumptions
The mass density and relative proportions of the airplane are unchanged - it's just bigger.Assume the wings work solely by the Bernoulli effect.
