4 cards from this section. Quick, good the night before a test.
What are the two primary forces acting on open channel flow?
Think about the forces affecting water movement.
Define hydraulic radius.
Consider what A and P represent.
What type of flow is characterized by constant parameters over a distance?
Consider what happens if flow characteristics do not change.
True or False: Friction is the only force acting against flow in open channels.
Recall the forces discussed at the beginning.
An open channel has a width of 5 meters and a depth of 3 meters. If the flow velocity is 2 m/s, calculate the discharge and hydraulic radius. Also, discuss how these parameters influence energy loss.
Determine A and P carefully, and remember the relationships for discussing energy loss.
In a rapidly varied flow scenario, how would you approach calculating the energy loss when a dam gate is lowered? What factors would influence your calculations?
Consider how abrupt changes affect energy and how to model the changes effectively.
