3 cards from this section. Quick, good the night before a test.
What is the Froude number?
Think about how it relates flow velocity to wave speed.
What happens at Fr < 1?
Consider how wave behaviors change with fluid speeds.
What is the Froude number equation?
Focus on the variables involved with wave and fluid speeds.
True or False: If the Froude number is equal to 1, the waves are stationary.
Consider what happens when flow speed matches wave speed.
A river has a depth of 2 m, and waves travel at 3.5 m/s. Calculate the Froude number and specify if the flow is subcritical or supercritical.
Use g = 9.81 m/s² for calculations.
If a wave has a finite amplitude of 0.5 meters in a channel of depth 1.5 meters, how does this affect the speed compared to a wave with small amplitude?
