Reference no: EM13888360

An airship is to operate in air at 20oC and 1 bar at 20 m/s speed. A model of scale 1/20 is used for tests in a wind tunnel, the test speed being 75 m/s. Determine the pressure of the tunnel for dynamic similarity. The air temperatures are equal. If the drag force on the model was 250 N. Determine the drag on the prototype
