Agolf 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 dimensionless 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 200ft/s? (50ft/s) (c) what rotation speed must be used if the regular ball rotates at 60 revolutions per second? (3.75rps)
