5 cards from this section. Quick, good the night before a test.
What is the formula for calculating discharge in a rectangular channel?
Think of how area is calculated in terms of width and depth.
Define critical depth in your own words.
Consider how energy relates to flowing water.
What does $ rac{dy}{dx}$ signify?
Consider what is being measured in a flowing stream.
True or False: A steep slope will always produce a gradually varied flow.
Reflect on different flow conditions.
A rectangular channel has a width of 5m and a depth of 1.2m with a discharge of 2m³/s. Calculate the normal depth using Manning's equation with n = 0.015.
Remember that for a rectangular channel, A = b * y, and R can be related to A and wetted perimeter.
Describe the physical significance of $ rac{dy}{dx}$ being much less than 1.
Think about flow profiles and their relationship to water depth.
