Aerospace Engineering > GATE 2024 > Wind Tunnel Testing
It is desired to estimate the aerodynamic drag, D, on a car traveling at a speed of 30 m/s. A one-third scale model of the car is tested in a wind tunnel following the principles of dynamic similarity. The drag on the scaled model is measured to be Dm. The ratio D/Dm is _______ (rounded off to 1 decimal place).
Correct : 1
