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.

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.
