4 cards from this section. Quick, good the night before a test.
Define specific energy in the context of fluid mechanics.
Think about how flow depth and velocity contribute to energy.
What is critical depth and why is it important?
Consider the role of the Froude number.
What is the relationship between specific energy and flow depth?
Consider how energy consists of components that depend on depth.
True or False: A hydraulic jump only occurs in subcritical flow.
Think about the definitions of flow types.
A rectangular channel has a width of 10 m, and a discharge rate of 15 m³/s. Calculate the critical depth and the specific energy at this flow rate.
Start with the flow area and determine the necessary flow parameters.
Discuss how energy losses in hydraulic jumps can be minimized during design proceedings for a spillway.
Consider the flow characteristics that lead to hydraulic jumps.
