1.1. Laplace Equation

Try these first

1. 1.

   What is the two-dimensional flow visual representation called?

   Hint

   Look for a term that combines flow direction with potential differences.

2. 2.

   What is an equipotential line?

   Hint

   Think of areas where pressure remains constant.

3. 3.

   What do equipotential lines indicate?

   • Points of equal hydraulic head
   • Direction of fluid flow
   • Neither

   Hint

   Remember, these lines help identify regions with no flow.

4. 4.

   True or False: Flow lines can intersect each other.

   • True
   • False

   Hint

   Think about fluid dynamics.

5. 5.

   Given a flow channel where the head drop (Δh) is 10 m over a length (L) of 50 m with a uniform permeability k = 1.5, calculate the flow rate.

   Hint

   Use the parameters provided to find the flow using the formula derived from the concept.

6. 6.

   Describe how you would use flow nets to optimize the flow rate in a water treatment facility.

   Hint

   Think about changes in shape or barriers that affect flow rates.
