Challenge Problems
Push your limits with advanced challenges
A flat plate experiences airflow at a uniform velocity of 20 m/s. Determine the boundary layer thickness at a distance of 0.5 m from the leading edge, assuming water flows over the plate.
💡 Hint: Use typical values for water's density and viscosity.
Analyze how increasing the Reynolds number from 200,000 to 800,000 affects the layer characteristics of flow past a flat plate. Describe the physical implications.
💡 Hint: Think about the relationship between turbulence and particle interactions.
