Challenge Problems
Push your limits with challenges.
Question 1
Given a pipe diameter of 0.1 meters, find the roughness height if the velocity at 0.04m from the wall is 40% greater than that at 0.01m from the wall.
💡 Hint: Formulate expressions using the velocity ratios and refer to known equations for turbulent flow.
Question 2
Evaluate the behavior of turbulent flow as Reynolds number increases, considering both velocity and pressure changes.
💡 Hint: Analyze flow behaviors at critical transition points and use visual flow representations if necessary.
