2. Two-dimensional Flow

Try these first

1. 1.

   What are equipotential lines?

   Hint

   Think about where water stays the same level.

2. 2.

   What is the space between two flow lines called?

   Hint

   It's where the water flows through!

3. 3.

   What do flow nets consist of?

   • Only flow lines
   • Only equipotential lines
   • Both flow and equipotential lines

   Hint

   Recall the two components we've discussed!

4. 4.

   True or False: Equipotential lines can intersect.

   • True
   • False

   Hint

   Think of what happens at the same level!

5. 5.

   Calculate the total flow rate across a field with a total head drop of 10 meters, divided into 5 channels with a permeability of 3 m/s.

   Hint

   Spread the head drop across the channels.

6. 6.

   Draw and annotate a flow net for a rectangular embankment with given head levels at its boundaries.

   Hint

   Start with the boundary conditions before sketching!
