2 cards from this section. Quick, good the night before a test.
Define subcritical flow.
Consider the influence of gravity and inertia.
What does a Froude number of 1 indicate?
Think about what happens at the balance point.
What Froude number defines supercritical flow?
Think about which forces dominate.
True or False: Critical flow occurs when gravity forces are greater than inertia forces.
Consider the conditions defining critical flow.
A canal channel is designed to maintain a specific Froude number for effective flow. If the channel depth is varied, how would you determine the width needed to keep a constant discharge? Provide calculations.
Use the equations related to flow area and Froude's number.
Consider a scenario where a hydraulic jump occurs. Analyze the energy loss and effects of flow depth before and after the jump. Provide a detailed explanation.
Examine the relationship between Froude numbers and flows.
