Question 1.
What is the formula for calculating hydraulic radius?
Show hintHide hint
Remember, it's about flow area and perimeter.
Question 2.
Describe what specific energy represents in fluid mechanics.
Show hintHide hint
Think about energy and depth!
3Question 3.
What does the hydraulic radius (R) help determine?
- Flow depth
- Flow velocity
- Wetted perimeter
Show hintHide hint
Think about how radius affects flow!
4Question 4.
True or False: The Froude number only classifies flow as either subcritical or supercritical.
- True
- False
Show hintHide hint
Consider all categories of flow.
Question 5.
In a trapezoidal channel with a fixed discharge, how can changing the channel base width affect flow characteristics? Discuss the hydraulic radius implications.
Show hintHide hint
Consider the definitions of area and perimeter.
Question 6.
Calculate the specific energy at a flow depth of 3 m and velocity of 5 m/s. Discuss implications for channel design.
Show hintHide hint
Use the specific energy formula to find E.
