Question 1.
What is viscous flow?
Show hintHide hint
Think about how thick liquids behave.
Question 2.
What is the main driving force for flow in pipes?
Show hintHide hint
Consider how water flows through a pipe.
3Question 3.
What type of flow is characterized by a Reynolds number below 2100?
- Turbulent
- Laminar
- Transitional
Show hintHide hint
Think about the flow characteristics at low speeds.
4Question 4.
True or False: The pressure gradient is the primary driving force for flow in open channels.
- True
- False
Show hintHide hint
Recall how fluids behave in open channels.
Question 5.
A fluid flows through a long, smooth pipe at a velocity of 1 m/s. If the diameter of the pipe is doubled, how does the Reynolds number change assuming viscosity stays the same?
Show hintHide hint
Remember the Reynolds number formula: Re = (density × velocity × diameter) / viscosity.
Question 6.
Design an experiment to demonstrate the transition from laminar to turbulent flow using water and a dye. Describe the setup and the expected observations.
Show hintHide hint
Focus on the visualization aspects with dye to observe the patterns.
