Question 1.
Define bulk flow in your own words.
Show hintHide hint
Think about how substances move in a river.
Question 2.
What is molecular diffusion?
Show hintHide hint
Consider how smells spread in the air.
3Question 3.
What does bulk flow refer to?
- Mixing of chemicals
- Movement due to flow velocity
- Diffusion only
Show hintHide hint
Focus on the movement of fluid and not chemical mixing.
4Question 4.
True or False: In a lake's deeper areas, bulk flow predominates.
- True
- False
Show hintHide hint
Consider the effects of wind only occurring at the surface.
Question 5.
A river is flowing with a velocity of 2 m/s carrying a pollutant downstream. If the concentration of the pollutant is 5 mg/L, calculate the approximate total flux of pollution in the river flow.
Show hintHide hint
Multiply the velocity by concentration to find the flux.
Question 6.
Discuss the potential impacts of changing groundwater velocities due to increased rainfall on pollutant transport in a saturated zone.
Show hintHide hint
Consider how changes to flow could alter the mass transport processes.
