Question 1.
What is laminar flow?
Show hintHide hint
Think about how liquids flow in different situations.
Question 2.
What does a low Reynolds number indicate?
Show hintHide hint
Recall the definition of Reynolds number.
3Question 3.
What describes laminar flow?
- Fluid moves chaotically
- Fluid moves in layers
- Fluid is turbulent
Show hintHide hint
Think about how different fluids can flow.
4Question 4.
True or False: A high Reynolds number indicates laminar flow.
- True
- False
Show hintHide hint
Recall what Reynolds number signifies.
Question 5.
A pollution control system uses pumps to maintain laminar flow in a river. If the system doubles the velocity, how will that affect mass transfer resistance and pollutant dispersion?
Show hintHide hint
Consider how convection relates to diffusion.
Question 6.
Calculate the diffusion coefficient for a substance given the medium’s properties: if the medium's viscosity increases, what trend will you expect in the diffusion coefficient and why?
Show hintHide hint
Think about how viscosity affects fluid dynamics.
