Question 1.
Define specific energy in your own words.
Show hintHide hint
Think about how depth and velocity relate.
Question 2.
What is the continuity equation used for?
Show hintHide hint
Consider the relationship between area and velocity.
3Question 3.
What is specific energy in open channel flow?
- Only potential energy
- Only kinetic energy
- Total energy per unit weight
Show hintHide hint
Remember the components that make it up.
4Question 4.
True or False: The continuity equation states that mass is conserved in fluid flow.
- True
- False
Show hintHide hint
Think about mass flow rates before and after any section.
Question 5.
A rectangular channel has a water depth of 3 ft and a flow velocity of 4 ft/s. Calculate the specific energy and determine what happens if the depth increases to 4 ft.
Show hintHide hint
Use the depth values in the specific energy equation.
Question 6.
Given a channel that widens from 5 ft to 10 ft, and initial velocity is 6 ft/s, calculate the new velocity using continuity. Discuss the effect on specific energy.
