2 cards from this section. Quick, good the night before a test.
What is the no slip boundary condition?
Think about how fluids interact with solid surfaces.
What type of flow remains constant in depth and velocity along a channel?
Remember the definition of uniformity in flow characteristics.
What is the velocity at the boundary under the no slip condition?
Recollect the definition of this condition.
Gradually varied flow indicates a rapid change in flow parameters.
Think about the term 'gradual'.
A river has a width of 10 meters and a maximum depth of 2 meters. Based on velocity distribution principles, estimate the average velocity near the center of the flow if the boundary velocity is zero.
Think about how fast the water would move in the center compared to edges.
Consider a rapidly varied flow scenario in a flood channel. Describe how this would impact the surrounding landscape and the design of nearby structures.
Remember the impact of sudden flow variations on velocity and shear.
