Astudent 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.
