Question 1.
What formula do you use to calculate gravitational acceleration from wave speed?
Show hintHide hint
Consider how wave speed relates to gravity.
Question 2.
What does a Froude number less than 1 indicate?
Show hintHide hint
Recall flow conditions and impacts.
3Question 3.
What formula relates wave speed and depth to gravitational acceleration?
- g = V/y
- g = V²/y
- g = V/y²
Show hintHide hint
Square the speed and adjust with depth.
4Question 4.
True or False: A Froude number greater than 1 indicates subcritical flow.
- True
- False
Show hintHide hint
Consider the flow dynamics involved in critical transitions.
Question 5.
A channel with a width of 1.5 m carries a flow of 5 m³/s at a depth of 1 m. Calculate and analyze the critical depth and specific energy for this scenario.
Show hintHide hint
Use appropriate equations for critical flow analysis.
Question 6.
In a hypothetical scenario, a lake is 2 m deep and waves travel at 3.6 m/s. Determine the gravitational acceleration and discuss the density implications.
Show hintHide hint
Think through how gravity influences density and behavior in aquatic systems.
