Challenge Problems
Push your limits with challenges.
Question 1
If a liquid with a dynamic viscosity of 0.5 Pa.s is flowing through a pipe with a diameter of 10 cm at a speed of 1 m/s, calculate the Reynolds number for this flow condition. What does this indicate about the flow type?
💡 Hint: Use the formula for Reynolds number and check the criteria for laminar versus turbulent flow.
Question 2
Discuss how the viscosity of a fluid can be reduced in industrial applications. Provide examples of how this impacts flow in pipelines.
💡 Hint: Consider why industries might want to transport fluids quickly.
