2 cards from this section. Quick, good the night before a test.
What is the formula for mass flow rate?
Remember it includes density, width, velocity, and depth.
What does the Froude number indicate?
Think about the relationship of velocities.
What is the relationship between wave speed and fluid depth?
Use the formula to analyze this.
True or False: The Froude number is greater than 1 in subcritical flow.
Think about the definitions of subcritical and supercritical flows.
A wave travels with speed c = 3 m/s over a 2-meter deep pond. If the wave speed increases by 1 m/s, what is the new depth assuming constant gravity?
Root values apply to both situations. Set their equations equal and solve.
In a channel, fluid depth is increased from 1.5m to 3.0m. Calculate the change in wave speed assuming gravity remains constant.
Utilize the wave speed formula and substitute values in.
