3 cards from this section. Quick, good the night before a test.
What does DNAPL stand for?
Remember, it's related to spill scenarios in water.
Why does a DNAPL sink in water?
Think about how the atom arrangement affects density.
What characteristic defines a DNAPL?
Think about what happens when you pour oil in water.
True or False: Mass transfer only occurs in still water.
Consider a river current compared to a pond.
A barge spills chlorinated solvent into a river. Describe the expected behavior of the solvent and the implications for sediment.
Consider the properties of both the solvent and the river's flow.
Calculate the flux of a DNAPL from sediment to water given the concentration in sediment as 200 mg/L and equilibrium concentration in water as 50 mg/L with a mass transfer coefficient of 0.1 cm/s.
Think about what a negative flux can imply in terms of movement.
