1.1. Introduction to Laminar and Turbulent Flow

Try these first

1. 1.

   Define laminar flow.

   Hint

   Think of how water flows in a straight pipe.

2. 2.

   What happens to fluid flow at low velocities?

   Hint

   Recall the Reynolds number context.

3. 3.

   What is called when the flow appears smooth and orderly?

   • Laminar
   • Turbulent
   • Transitional

   Hint

   Which kind of flow do we see in straws?

4. 4.

   True or False: Turbulent flow is characterized by chaotic changes.

   • True
   • False

   Hint

   Think about water in a storm.

5. 5.

   A fluid with a viscosity of 0.002 Pa·s flows through a pipe of diameter 0.05 m at a velocity of 4 m/s. Calculate the Reynolds number and determine the flow regime.

   Hint

   Use the formula and remember the critical number.

6. 6.

   Discuss a real-life application where controlling flow type (laminar vs turbulent) is crucial and explain why.

   Hint

   Think about the implications of each flow type on health.
