3 cards from this section. Quick, good the night before a test.
Calculate the area of a rectangular channel if the width is 5 meters and depth is 2 meters.
Use the formula A = width * depth.
What is the unit of discharge (Q)?
Think about volume flow rate.
What defines a rectangular channel's area of flow?
Recall the formula for area.
Is dy/dx always less than 1 in gradually varied flow?
Consider the meaning of gradually varied flow.
Establish the impact of increasing depth in a channel section on the discharge and rate of change of depth. What general conclusion can be drawn?
Look at the relationship between depth and how it expresses itself through the various equations.
Derive an equation that could relate the increasing bed slope with the energy loss in a channel when the discharge remains constant.
Think about how energy works in the forms of potential and kinetic in the flow equations.
