A 1/10th 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.
