Challenge Problems
Push your limits with advanced challenges
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.
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.
