3 cards from this section. Quick, good the night before a test.
What is the Froude number?
Think about how we measure flow dynamics.
Define subcritical flow.
What happens when the Froude number is less than one?
What classifies flow as subcritical?
Think about the relationship between gravity and inertia.
True or False: Disturbances in supercritical flow propagate upstream.
Consider how wave speed is affected by flow regime.
A river has an average velocity of 4 m/s and a depth of 2 m. Determine the Froude number and categorize the flow.
Use the Froude number formula.
How would the introduction of a dam influence flow regime transitions in a river?
Think about how energy changes with depth.
