3 cards from this section. Quick, good the night before a test.
Define mass balance in your own words.
Think about how inputs and outputs relate.
What is evaporation?
Consider what happens to water in a pot on the stove.
What does the mass balance equation express?
Focus on the relationship between what's coming in and going out.
True or False: Evaporation plays no role in the mass balance of pollutants.
Remember how pollutants can enter the air.
A factory continuously admits 500 kg of a pollutant every week into a lake while 200 kg are evaporated. Calculate the total mass of the pollutant after 4 weeks and discuss the implications.
Use the mass balance equation to track inputs and outputs.
If the lake has an initial concentration of 4400 kg of a pollutant and it is diluted by a rainfall of 1000 cubic meters with a clean water influx, what happens to the concentration?
Consider how dilution works when additional water is introduced.
