Challenge Problems
Push your limits with advanced challenges
A flat plate in air flow shows a boundary layer of 1.5 mm at a velocity of 5 m/s. If the viscosity of air is 1.8 × 10^-5 Pa.s, calculate the shear stress at the wall.
💡 Hint: Determine the gradient near the wall using velocities.
If a wind tunnel with a diameter of 30 cm is designed for laminar flow at a speed of 4 m/s, what will be the Reynolds number? Will the flow remain laminar or transition to turbulence?
💡 Hint: Calculate using viscosity and density at the given temperature.
