2 cards from this section. Quick, good the night before a test.
Define the Froude number.
Remember that it's a ratio of flow velocity to wave speed.
What is specific energy?
Think about how you would express energy in terms of depth and velocity.
What is the flow regime when the Froude number is less than 1?
Think about the characteristics of wave speed related to flow speed.
True or False: Hydraulic jumps are beneficial for managing flow in channels.
Recall the discussion on energy losses and their applications.
Design an open channel with a width of 5m and a depth of 2m. Calculate the Froude number if the flow velocity is 3 m/s.
Apply the Froude number formula.
If a hydraulic jump occurs and the specific energy before the jump is 3m, while after the jump is 2.4m, what is the energy loss?
Remember the energy loss calculation discussed in class.
