6. Long-Term Environmental Monitoring

Try these first

1. 1.

   Define the Sherwood number.

   Hint

   Think about how transport occurs in fluids.

2. 2.

   What does the Reynolds number indicate?

   Hint

   Consider the forces acting on the fluid.

3. 3.

   What does the Sherwood number (NSh) represent?

   • Ratio of inertia to viscosity
   • Ratio of convective to diffusive mass transport
   • Amount of mass lost in a spill

   Hint

   Focus on how mass moves in different environments.

4. 4.

   True or False: A higher Reynolds number indicates a laminar flow regime.

   • True
   • False

   Hint

   Consider the flow characteristics.

5. 5.

   Given a river with measured velocities high enough to present a Reynolds number greater than 2000, discuss the implications for pollutant dispersion in the water and compare them to a lake with a low Reynolds number.

   Hint

   Consider how flow dynamics alter dispersion effectiveness.

6. 6.

   How would you assess the environmental monitoring strategy if pollution from a spill resulted in varying Schmidt numbers due to temperature differences?

   Hint

   Think about the effect of environmental factors on monitoring efficacy.
