2 cards from this section. Quick, good the night before a test.
What is the formula to calculate the acceleration due to gravity based on wave speed?
Consider how waves are generated in the medium.
What defines a subcritical flow in terms of the Froude number?
Reflect on the physical meanings of inertia and gravity.
What is the Froude number used for?
Consider its relationship with inertia and gravity.
True or False: Specific energy is the sum of the depth and kinetic energy head.
Keep in mind the components of energy.
A triangular channel has a bottom width of 4 meters and a slope of 2:1. If it carries a discharge of 12 m³/s, calculate the critical depth and discuss how it varies with changes in discharge.
Utilize the relevant equations derived for triangular channels.
You have two channels with different slopes but identical discharge. Analyze how the different slopes impact the Froude number and flow type in both channels.
Recall the Froude number's dependence on velocity and channel depth.
