A1/10th scale model of an airplane is to be tested in a wind tunnel that operates with air at a pressure of 20 atmospheres. the plane is expected to fly at a speed of 500 [km/hr]. (a) what speed should the wind tunnel be run? (b) if the drag measured on the model is 337.5 [n], what is the corresponding drag on the full size airplane? recall that the viscosity is effectively independent upon pressure changes.
