14.4.1. Flow Conditions

Try these first

1. 1.

   What is the definition of open channel flow?

   Hint

   It involves a free surface.

2. 2.

   Name the two main forces acting on open channel flow.

   Hint

   They are opposed to each other.

3. 3.

   What describes open channel flow?

   • Flow in pipes
   • Flow with free surface
   • Both A and B

   Hint

   Remember, it's not confined.

4. 4.

   Rapidly varied flow occurs when:

   • True
   • False

   Hint

   Think of sudden flow interruptions.

5. 5.

   Given a rectangular channel with a width of 10 meters and a depth of 2 meters, calculate the hydraulic radius.

   Hint

   Remember the hydraulic radius formula.

6. 6.

   Discuss why rapidly varied flow may present challenges in open channel design.

   Hint

   Consider how a sudden change in flow impacts channel stability.
