4 cards from this section. Quick, good the night before a test.
Define the Froude number and its significance in fluid flow.
Recall the formula that defines this number.
What happens to flow when it undergoes a hydraulic jump?
Think of the Froude number relation.
What does a Froude number greater than 1 indicate?
Recall our earlier discussions on flow regimes.
Is energy loss in a hydraulic jump due to friction?
Think about what the calculations aim to show.
A hydraulic jump occurs where Fr1 = 8.5. Given y1 = 0.3m, derive y2 and the energy loss.
Ensure your calculations follow the correct sequence!
Design a spillway having a jump with Fr1=5. What considerations must be taken into account for managing energy loss?
Think about all environmental aspects and structural integrity.
