3 cards from this section. Quick, good the night before a test.
Define specific energy.
Think about what components make up the total energy.
What is the Froude number used for?
Remember, it's a dimensionless number.
What does specific energy consist of?
Recall the components that make up total energy in fluid mechanics.
True or False: Subcritical flow occurs when the Froude number is greater than 1.
Think about the definitions we've discussed regarding flow regimes.
Design a canal section that can support a flow rate of 250 m³/s while maintaining critical flow conditions. Calculate the necessary width and depth.
Recall the critical depth equations and apply them to find optimal parameters.
Evaluate the implications of constructing a series of small dams on a river's course in terms of specific energy and flow conditions.
Think about how energy loss increases with changes in flow conditions and how it impacts fish and sediment transport.
