Challenge Problems
Push your limits with advanced challenges
For a laminar flow over a flat plate with the upper velocity of 10 m/s, calculate the displacement thickness at a position where the Reynolds number is 50,000, assuming constant viscosity.
💡 Hint: You might need to use the relationships provided in the lecture.
How does an increase in flow velocity impact the displacement thickness and what implications does this have on drag for an aerodynamic surface?
💡 Hint: Consider the relationship between Reynolds number and boundary layer characteristics.
