5. Case Studies and Problem Scenarios

Try these first

1. 1.

   Define the Sherwood number.

   Hint

   Think about how it defines different types of mass transfer.

2. 2.

   What formula do we use to calculate the Reynolds number?

   Hint

   Consider what factors influence flow dynamics.

3. 3.

   What does the Sherwood number represent?

   • A ratio of heat transfer
   • A ratio of convective mass transport to diffusive mass transport
   • A measure of viscosity

   Hint

   Think about how mass spreads in different environments.

4. 4.

   True or False: DNAPLs always float on water.

   • True
   • False

   Hint

   Recall the definitions of DNAPLs and LNAPLs.

5. 5.

   Calculate steady-state mass transport flux given varying concentrations and temperatures for an oil spill incident.

   Hint

   Remember to account for both diffusion and convective factors in your calculations.

6. 6.

   Design an experiment to measure the impact of wind speed on oil spill dispersion in a lake.

   Hint

   How will you simulate wind conditions, and what variables will you measure?
