1.2. Constant Determination

Try these first

1. 1.

   What is the Laplace Equation used for?

   Hint

   Think about fluid mechanics.

2. 2.

   What do equipotential lines represent?

   Hint

   Consider their role in hydraulic head.

3. 3.

   What does the Laplace equation help to determine?

   • Flow patterns in fluids
   • Chemical reactions
   • Temperature variations

   Hint

   Think about what it models in physics.

4. 4.

   Two flow lines can intersect with each other.

   • True
   • False

   Hint

   Recall the flow net properties.

5. 5.

   A flow net shows three equipotential lines and two flow lines. Calculate how many flow channels exist.

   Hint

   Count the spaces created between the lines.

6. 6.

   A soil has a permeability of 5 m/day, and the distance between equipotential lines is 0.5 m. Calculate the flow rate through a flow channel with a total head drop of 2 m.

   Hint

   Substitute the values into the flow equation.
