Testing golf ball aerodynamics.? how?

AI Thread Summary
To test the aerodynamic properties of golf balls with varying surfaces, one suggested method involves using liquid to observe airflow differences, similar to a referenced video. The goal is to compare the airflow around a textured ball to that of a smooth-surfaced ball. Participants are encouraged to explore alternative testing methods or variations of the liquid approach. Clarification on specific aerodynamic properties to measure is also sought. This discussion focuses on practical testing techniques for golf ball aerodynamics.

Testing golf ball aerodynamics.? how?

i need a simple way to test the aerodynamic properties of spheres with different surfaces.

i was thinking of doing it with liquid as in this video

is there any other way i can do it or perhaps a way i can do it the way they do it in the video

please help

What properties are you trying to calculate/test for?

Thanks

merely the airflow difference around the ball (shape). so i can compare it with that around a smooth surfaced ball.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
