Question 1.
What characterizes laminar flow?
Show hintHide hint
Think of a slow-moving liquid.
Question 2.
What happens to a smoke plume from a candle as it rises?
Show hintHide hint
Recall the transition from ordered to disordered flows.
3Question 3.
What is the critical Reynolds number value that suggests laminar flow?
- 4000
- 2300
- 3000
Show hintHide hint
Think about low velocity flows.
4Question 4.
True or False: All flows in nature are turbulent.
- True
- False
Show hintHide hint
Recall examples of both flow types.
Question 5.
A liquid with a density of 850 kg/m³ flows through a pipe with a diameter of 0.05 m at an average velocity of 1.5 m/s. Calculate the Reynolds number and determine if the flow is laminar or turbulent.
Show hintHide hint
Ensure you use the correct relationship for viscosity.
Question 6.
How would decreasing the flow velocity in a piping system impact the flow regime? Discuss the transition from turbulent to laminar flow.
Show hintHide hint
Consider how flow velocities affect the Reynolds number's value.
