Show hintHide hint
Consider what turbulent flow means for fluid behavior.
3Question 3.
What is the Sherwood number a measure of?
- A) Ratio of mass diffusion rates
- B) Ratio of convective to diffusive mass transport
- C) Measure of fluid viscosity
Show hintHide hint
Think about what processes occur in fluid dynamics.
4Question 4.
True or False: A high Reynolds number indicates laminar flow.
- True
- False
Show hintHide hint
Recall what laminar flow means.
Question 5.
A river flows at a velocity of 3 m/s. If the characteristic length of the river is 1.5 m and the viscosity of the water is 0.001 Pa·s, calculate the Reynolds number.
Show hintHide hint
Use the Reynolds number formula.
Question 6.
Discuss the implications of using an average characteristic length when calculating the Sherwood number in varying flow conditions in a natural water body.
Show hintHide hint
Think about the variability in flow conditions.
