Question 1.
What is the formula for calculating acceleration due to gravity based on wave speed?
Show hintHide hint
Recall the relationship between wave speed, depth, and gravity.
Question 2.
What Froude number indicates subcritical flow?
Show hintHide hint
Consider what happens when flow is slow.
3Question 3.
What formula is used to calculate acceleration due to gravity based on wave speed?
- A. g = V / y
- B. g = V² / y
- C. g = V³ / y²
Show hintHide hint
Remember the relationship between velocity, gravity, and depth.
4Question 4.
A Froude number less than 1 indicates what type of flow?
- True
- False
Show hintHide hint
Think of what characterizes slow flows in channels.
Question 5.
In a rectangular channel 2 m wide with a flow depth of 1.5 m, if the discharge is 12 m³/s, determine the critical depth and evaluate how it would change with a modified depth of 1 m.
Show hintHide hint
Use the critical depth equation based on discharge and gravity.
Question 6.
Analyze the role of submerged vegetation in modulating flow speed and its critical depth in a stream and discuss implications for aquatic life.
Show hintHide hint
Think about how vegetation alters flow patterns negatively or positively.
