Challenge Problems
Push your limits with advanced challenges
A fluid with a density of 800 kg/m³ and a dynamic viscosity of 0.002 Pa·s flows through a pipe of diameter 0.05 m at a velocity of 4 m/s. Determine whether the flow is laminar, transitional, or turbulent.
💡 Hint: Calculate Reynolds number to classify the flow.
Describe an engineering situation where turbulence would be ideal, and explain why.
💡 Hint: Consider applications that benefit from increased mixing or contact area.
