Interactive Quizzes

Quick quizzes to reinforce your learning

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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
