Challenge Problems
Push your limits with challenges.
Question 1
A fluid with a kinematic viscosity of 1 x 10^-6 m^2/s flows over a horizontal flat plate with a length of 3 m at a velocity of 2.5 m/s. Determine the Reynolds number and state whether the flow is laminar or turbulent.
💡 Hint: Apply the Reynolds number formula.
Question 2
In a scenario where the fluid flow transitions from laminar to turbulent, outline the practical implications in engineering design fields such as pipelines or aircraft wings.
💡 Hint: Explore design factors that are influenced by flow types.
