Challenge Problems
Push your limits with challenges.
Question 1
A flat plate in a fluid stream experiences a transition from laminar to turbulent flow. Analyze the implications for drag force if the Reynolds number increases significantly.
💡 Hint: Consider how flow dynamics change with turbulence.
Question 2
Calculate the boundary layer thickness delta at x = 2 m, given a free stream velocity U of 10 m/s and kinematic viscosity nu of 1 x 10^-6 m²/s.
💡 Hint: Use the relation provided for calculating delta based on free stream velocity and viscosity.
