A golf ball manufacturer wants to study the effects of dimple size on the performance of a golf ball. A model ball four times the size of a regular ball is installed in a wind tunnel. (a) What parameters must be controlled to model the golf ball performance? (b) What should be the speed of the wind tunnel to simulate a golf ball speed of 200 ft/s? (c) What rotational speed must be used if the regular ball rotates at 60 revolutions per second?
