A student needs to measure the drag on a prototype of characteristic dimension dp moving at velocity Up in air at standard atmospheric conditions. He constructs a model of characteristic dimension dm, such that the ratio dp/dm is some factor f . He then measures the drag on the model at dynamically similar conditions (also with air at standard atmospheric conditions). The student claims that the drag force on the prototype will be identical to that measured on the model. Is this claim correct?
