1.1. Laminar and turbulent flow (Cond.)

Try these first

1. 1.

   Explain what laminar flow is.

   Hint

   Think about how layers move in one direction without mixing.

2. 2.

   What is a key factor that determines the flow type?

   Hint

   Recall what Reynolds number compares.

3. 3.

   What type of flow is characterized by smooth and orderly motion?

   • Turbulent
   • Laminar
   • Transitional

   Hint

   Think how fluid layers behave.

4. 4.

   The Reynolds number helps determine flow type. True or False?

   • True
   • False

   Hint

   Reflect on fluid dynamics principles.

5. 5.

   Design an experiment to test the transition point of laminar to turbulent flow utilizing the Reynolds number.

   Hint

   Think of how you could adjust water speed and observe dye movement.

6. 6.

   Find the terminal velocity of a sphere of diameter 0.02 m falling in water at a given viscosity.

   Hint

   Remember, terminal velocity occurs when forces are balanced.
