Challenge Problems
Push your limits with challenges.
Question 1
Given a pipe flow scenario with a diameter of 0.1 m, determine the Reynolds number if the fluid has a density of 1000 kg/m³ and flows at a velocity of 5 m/s with a dynamic viscosity of 0.001 Pa.s. Is the flow laminar, transitional, or turbulent?
💡 Hint: Use the formula for Reynolds number.
Question 2
Discuss how energy cascades from large eddies to small eddies, highlighting the role of viscosity in this process.
💡 Hint: Think about the implications of size on energy.
