Question 1.
What is turbulent flow?
Show hintHide hint
Think about smooth versus chaotic motion in water flow.
Question 2.
What does surface roughness affect?
Show hintHide hint
Consider how a smooth glass pipe vs. a rough metal pipe would behave.
3Question 3.
What type of flow is characterized by chaotic motion?
- Laminar
- Turbulent
- Steady
Show hintHide hint
Think about how water flows rapidly in a river.
4Question 4.
True or False: Surface roughness does not impact the flow velocity in pipes.
- True
- False
Show hintHide hint
Remember our discussion about smooth versus rough surfaces.
Question 5.
A rough pipe of 12 cm diameter has a flow velocity measured at a point 5 cm from the wall that is 50% higher than at a point 2 cm from the wall. Calculate the average height of roughness k and discuss its implications.
Show hintHide hint
Identify the ratios of velocities to set up your equations.
Question 6.
Discuss how velocity field predictions from these models can impact real-world applications like water treatment facilities or HVAC systems.
Show hintHide hint
Focus on industries where flow assessment is key to product performance.
