You have been asked by a baseball manufacturer to study how certain stitching patterns on a baseball prototype affect travel distance. using principles of dynamic similarity, you make a baseball model that is three times the size of a regular baseball and you place it in a wind tunnel. you remember from fluid mechanics that the reynolds (re) number is important to this problem (see class notes for re number derivation).
