2 cards from this section. Quick, good the night before a test.
What is the formula for specific energy?
Think about the components that make up total energy in fluid.
Define head loss in terms of open channel flow.
Consider how energy is dissipated in flowing water.
What does the specific energy equation represent?
Think about what you need to maintain flow.
True or False: The specific energy is always constant along a flow channel.
Consider factors impacting energy as water flows.
A rectangular channel has a width of 3 m. If the discharge is 9 m³/s, calculate the critical depth, specific energy, and Froude number.
Use both critical flow and specific energy equations for iterative resolution.
Given a sloped channel with a head loss of 0.3 m over 10 m, how does this affect the energy at two points?
Don’t forget the relationship between energy losses and flow distance!
