An airplane wing, with chordlength of 5 ft and span of 30 ft. is designed to fly in standard air at a speed of 230 ft/sec. A 1/10 scale model of this wing is to be tested in a water tunnel. What flow speed is necessary in the water tunnel to achieve dynamic similarity? What will theratio of drag forces measured in the model flow to those on the prototype wing be? Ignore compressibility
