What is the formula for wave speed in small amplitude waves?
Think about how waves are related to gravity and fluid depth.
Define subcritical flow.
Consider the relationship between wave speed and fluid speed.
What is the final equation for wave speed in small amplitude waves?
Recap the connection between wave speed and gravity.
True or False: In subcritical flow, the wave can travel upstream.
Recall the definitions of flow types.
A 4-meter deep river generates solitary waves at a speed of 7 m/s. What is the value of g on this planet?
Use the equation to solve for g based on given values.
A drainage channel operates at 2 m depth and has waves with an amplitude of 0.5 m. Calculate the speed of the waves.
Substitute values into the finite size equation.
