Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What happens to the flow when the Reynolds number exceeds 4000?

  • It remains laminar.
  • It becomes turbulent.
  • It becomes transitional.

💡 Hint: Consider the classification of flows based on Reynolds number thresholds.

Question 2

Is the statement true or false: A Reynolds number of less than 2300 indicates turbulent flow.

  • True
  • False

💡 Hint: Review the threshold definitions provided.

Challenge Problems

Push your limits with challenges.

Question 1

For a fluid with a density of 850 kg/m³ and dynamic viscosity of 0.002 Pa.s flowing at a velocity of 1.5 m/s in a pipe with a diameter of 0.1 m, calculate the Reynolds number and state the flow regime.

💡 Hint: Substitute the values carefully in the formula and remember the definitions.

Question 2

Discuss how varying the diameter of a pipe in a water supply system affects the Reynolds number and potential flow regimes encountered.

💡 Hint: Think about the equations you've learned regarding diameter and flow.
