Try these first

1. 1.

   What is the main difference between laminar and turbulent flow?

   Hint

   Think about how fluid layers move in each case.

2. 2.

   What does Reynolds number indicate?

   Hint

   Recall the threshold values we discussed.

3. 3.

   What type of flow occurs when the Reynolds number is below 2000?

   • Reynolds Flow
   • Laminar Flow
   • Turbulent Flow

   Hint

   Think about how layers of fluid interact.

4. 4.

   True or False: Turbulent flow is beneficial for mixing fluids.

   • True
   • False

   Hint

   Consider how turbulent flow behaves compared to laminar flow.

5. 5.

   Determine the diameter of a rough pipe if the average velocity is increased by a factor of 1.5 at a distance of 2 centimeters from the wall compared to a 1 centimeter distance.

   Hint

   Start by applying the velocity ratios discussed and solve the resulting equations.

6. 6.

   Design a test setup to measure the transition point from laminar to turbulent flow using a water reservoir and flow meter.

   Hint

   Consider how you will collect and analyze the data.
