16.5. Control Volume Analysis

Try these first

1. 1.

   What is a control volume?

   Hint

   Think about the area of interest for flow analysis.

2. 2.

   Define specific energy in fluid flows.

   Hint

   It involves flow depth and velocity.

3. 3.

   What does a control volume analyze?

   • Mass transmission
   • Fluid change
   • Conservation laws

   Hint

   Focus on the principles being applied.

4. 4.

   True or False: A hydraulic jump occurs when flow transitions from subcritical to supercritical.

   • True
   • False

   Hint

   Think about the flow conditions involved.

5. 5.

   You have a rectangular channel with a width of 8m and a depth of 3m. The flow velocity is 4m/s. Compute the specific energy and Froude number. What type of flow does this indicate?

   Hint

   Don’t forget the specific energy and Froude number formulas!

6. 6.

   A flow in a channel transitions from a Froude number of 2 to a Froude number of 0.5. Describe the changes in flow and potential energy loss.

   Hint

   Consider the definitions of supercritical and subcritical flow.
