Interactive Quizzes

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

Question 1

What is the formula for critical velocity (Vc)?

  • Vc = 0.55·D^0.64
  • Vc = 0.75·D^0.45
  • Vc = D^0.64

💡 Hint: Think about the components in the context of flow.

Question 2

True or False: Higher sediment sizes require lower velocities to remain in suspension.

  • True
  • False

💡 Hint: Recall the critical velocity ratio concept.

Challenge Problems

Push your limits with challenges.

Question 1

A channel has a flow depth of 4 meters. Calculate the critical velocity. Discuss the implications of not maintaining this speed.

💡 Hint: Apply the formula carefully considering flow depth.

Question 2

If the sediment is a mix with a ratio of m = 1.2, what does this indicate about the required critical velocity compared to normal? Provide reasoning.

💡 Hint: Relate it back to the original formula and effects of sediment type.
