Challenge Problems
Push your limits with challenges.
Question 1
In an experiment, the displacement thickness is measured to be 0.05 meters. If the flow rate is initially 10 cubic meters per second, calculate the new effective flow rate after considering δ*.
💡 Hint: Consider the principle of flow continuity.
Question 2
Discuss how the calculation of θ may differ in turbulent flow compared to laminar flow.
💡 Hint: Think about how turbulence increases complexity in determining flow characteristics.
