Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a flat plate in a flow with a speed of 5 m/s. Using the one-seventh power law, calculate the velocity at a point 0.02m within the turbulent boundary layer.

💡 Hint: You may need to determine the boundary layer thickness first based on flow conditions.

Challenge 2 Hard

Evaluate how the presence of a turbulent boundary layer affects the drag force on a large aircraft wing in cruise conditions.

💡 Hint: Review how turbulent layers generate drag compared to laminar layers.
