1.4. Experimental setup for studying laminar and turbulent flow

Try these first

1. 1.

   Define laminar flow.

   Hint

   Think of layers moving smoothly without mixing.

2. 2.

   What does the Reynolds number indicate?

   Hint

   Consider fluid behavior under different conditions.

3. 3.

   What type of flow occurs at Reynolds numbers below 2100?

   • Laminar flow
   • Turbulent flow
   • Transitional flow

   Hint

   Think of smooth and steady movement.

4. 4.

   True or False: Turbulent flow exhibits orderly streamlines.

   • True
   • False

   Hint

   Recall the nature of turbulent flow.

5. 5.

   Calculate the Reynolds number for oil with a density of 850 kg/m^3 and viscosity of 0.1 Pa.s flowing through a pipe of diameter 0.05 m at a velocity of 2 m/s. Determine whether the flow is laminar, transitional, or turbulent.

   Hint

   Use the Reynolds number formula; remember the definitions of flow types.

6. 6.

   In a scenario where you double the flow rate of water in a pipe, how does that affect the Reynolds number and flow type? Explain your reasoning.

   Hint

   Analyze how Reynolds number is affected by velocity and initially known conditions.
