1.3. Characteristics of Laminar and Turbulent Flow

Try these first

1. 1.

   Define laminar flow.

   Hint

   Think of how a calm river might flow.

2. 2.

   What is the critical Reynolds number for distinguishing laminar and turbulent flow?

   Hint

   This number is often used to categorize flow types.

3. 3.

   What is the primary characteristic of laminar flow?

   • Chaotic
   • Ordered
   • Random

   Hint

   Think about the definition of laminar flow.

4. 4.

   True or False: Turbulent flow occurs at low velocities.

   • True
   • False

   Hint

   Recall the relationship between velocity and flow type.

5. 5.

   A prism with a diameter of 10 cm is filled with water at a temperature of 20°C. If the average velocity of the water is 1 m/s, determine whether the flow is laminar, turbulent, or transitional. The kinematic viscosity of water at this temperature is 1.003 x 10^-6 m²/s.

   Hint

   Consider how you would set up the Reynolds number calculation.

6. 6.

   Design an experiment to transition a fluid from laminar to turbulent flow. Outline the parameters you would manipulate.

   Hint

   Think about both the physical characteristics of flow and external factors influencing it.
