22.6.4. Laminar Flow in Triangular Conduit

Try these first

1. 1.

   Define laminar flow.

   Hint

   Think about how layers of liquid might behave in a calm stream.

2. 2.

   What is the hydraulic diameter?

   Hint

   Consider how much flow area is in contact with the walls.

3. 3.

   What is laminar flow characterized by?

   • Turbulent mixing
   • Parallel layers of fluid
   • Random movement

   Hint

   Consider how water flows in a calm lake.

4. 4.

   True or False: The hydraulic diameter is only relevant for circular conduits.

   • True
   • False

   Hint

   Remember how we discussed its role in different shapes.

5. 5.

   Design a drainage system that uses triangular conduits for rainwater. Determine the required dimensions of the conduit to ensure laminar flow.

   Hint

   Consider flow rates and areas!

6. 6.

   Given an isosceles triangle conduit with two equal sides of length 5 m and a base of 4 m, determine the hydraulic diameter and discuss how this impacts laminar flow.

   Hint

   Draw a diagram to visualize the triangle.
