A student needs to measure the drag on a prototype of characteristic length dp moving at velocity Up in air at sea-level conditions. He constructs a model of characteristic length dm, such that the ratio dp/dm = a factor f. He then measures the model drag under dynamically similar conditions, in sea-level air. The student claims that the drag force on the prototype will be identical to that of the model. Is this claim correct? Explain.
