Challenge Problems

Push your limits with challenges.

Question 1

Given a turbulent flow measurement where the average velocity is 5 m/s and individual measurements range from 4.5 to 5.5 m/s, calculate the fluctuations and discuss how these could alter predictions in fluid dynamics.

💡 Hint: Use the individual measurements to determine the deviation from the average.

Question 2

In a study of turbulent flow in a river, describe how you would apply Reynolds Decomposition to analyze the flow data over a time interval.

💡 Hint: Think about the steps to derive the average and fluctuations from real measurement data.
