6.1. Generalized Correlation for Streams

Try these first

1. 1.

   What does DNAPL stand for?

   Hint

   Think about how this type of chemical behaves in water.

2. 2.

   What is a box model?

   Hint

   Consider how we break down complex environments.

3. 3.

   What is the main purpose of mass transfer coefficients?

   • To measure flow rate
   • To quantify substance movement
   • To track air quality

   Hint

   Remember the relationship between mass transfer and pollutants.

4. 4.

   Can DNAPLs float on water?

   • True
   • False

   Hint

   Consider the density properties of DNAPLs.

5. 5.

   Given a river system with a constant DNAPL spill, create a box model to predict the concentration of DNAPL in river water after one hour, considering flow velocity and mass transfer coefficients. Include at least three segments, detailing your assumptions.

   Hint

   Remember to consider how each section interacts and transfers material.

6. 6.

   Evaluate the impact of increased stream velocity on the mass transfer of a pollutant. Formulate a hypothesis based on your understanding of fluid dynamics.

   Hint

   Think about how fluid dynamics influences the behavior of pollutants.
