Question 1
What does the Reynolds number indicate?
- Ratio of inertial to viscous forces
- Total drag on the vehicle
- Air density
💡 Hint: Think about how it helps determine flow patterns.
Question 2
True or False: Higher drag coefficients result in lower drag forces.
- True

Challenge Problems
Push your limits with challenges.
Question 1
How would you design a test to effectively measure the aerodynamic efficiency of a new sports car model in a wind tunnel?
💡 Hint: Think about the parameters over which you have control.
Question 2
Given a drag coefficient increase from 0.3 to 0.4 while testing an automobile model at 50 km/h, calculate the expected increase in drag force if the frontal area remains constant.
💡 Hint: Use the drag equation to assess the difference with the new coefficient.
