Challenge Problems
Push your limits with advanced challenges
Given a flat plate in a turbulent flow, calculate the displacement thickness if the free stream velocity is 10 m/s at a point where the velocity profile shows 7 m/s at a distance of 0.5 m from the plate. Assume necessary values for Kinematic viscosity.
💡 Hint: Remember to account for the velocity deficit in your formula.
Explore how changing the surface roughness of an object affects the boundary layer characteristics and the applicability of the One-Seventh Power Law.
💡 Hint: Think about how rough surfaces influence flow dynamics and behavior.
