A one quarter scale model aircraft is tested at high incidence in a compressed air wind tunnel where the density is 10 times standard air density. It is found that the wings shed vortices at a frequency of 25 Hz. For conditions of dynamic similarity, what will be the equivalent vortex shedding frequency for the full-scale aircraft? You may assume that the air dynamic viscosity remains constant in model and full-scale conditions.
