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.
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.
