A prototype automobile is designed to travel at 65 km/hr.
Chapter 7, Problem 7.80(choose chapter or problem)
A prototype automobile is designed to travel at 65 km/hr. A model of this design is tested in a wind tunnel with identical standard sea-level air properties at a 1:5 scale. The measured model drag is 400 N, enforcing dynamic similarity. Determine (a) the drag force on the prototype and (b) the power required to overcome this drag. See Eq. 7.19.
