2.7. Dimensional Analysis of Flow

Try these first

1. 1.

   What type of flow occurs when viscosity has a significant effect?

   Hint

   Think about the fluid's thickness.

2. 2.

   What is the flow called when conditions do not change over time?

   Hint

   Consider a steady river flow.

3. 3.

   What type of flow has significant viscosity?

   • Viscous Flow
   • Inviscid Flow
   • Unsteady Flow

   Hint

   Consider fluid thickness.

4. 4.

   True or False: Turbulent flow is smooth and neat.

   • True
   • False

   Hint

   Think about how eddies behave.

5. 5.

   Design a scenario where you would switch from analyzing compressible flow to incompressible flow. Justify your approach.

   Hint

   Identify speed thresholds where density variations matter.

6. 6.

   Probe the transition from laminar to turbulent in a real-life scenario such as water discharge from a tap. Describe conditions yielding this transition.

   Hint

   Consider flow rates and velocities affecting transition.
