2 cards from this section. Quick, good the night before a test.
What is open channel flow?
Think about how rivers and streams behave.
What does a Froude number less than 1 indicate?
Consider the relationship between inertia and gravity.
What characterizes supercritical flow?
Think about the ratios of forces in motion.
True or False: In subcritical flow, disturbances can travel upstream.
Consider what happens in calm waters.
Calculate the Froude number for a river flow with a velocity of 3 m/s and a depth of 2 m. Is the flow subcritical, critical, or supercritical?
Remember to check the ratio against the Froude number criteria.
Discuss the implications of hydraulic jumps in a civil engineering project focused on canal construction. What designs need to change?
What happens to flow energy during transitions? Think about stability.
