A 1/10th scale model of a new automobile design is tested
Chapter 7, Problem 7.4C(choose chapter or problem)
A 1/10th scale model of a new automobile design is tested in a wind tunnel at the same Reynolds number as that of the full-scale prototype. The force coefficient (F/A)/\(\left(\frac{1}{2} \rho V^{2}\right)\) of the model is the same as that of the prototype. Assuming the model and prototype are both tested in air, the force on the scale model, \(\mathrm F_m\) is then
a) 1/10,000th that of the full-scale vehicle.
b) 1/1000th that of the full-scale vehicle.
c) 1/100th that of the full-scale vehicle.
d) 1/10th that of the full-scale vehicle.
e) The same as that of the full-scale vehicle.
