Question 1.
What is meant by mass balance in environmental engineering?
Show hintHide hint
Think about how materials are conserved in a closed system.
Question 2.
Why do we assume that rainwater has no contaminants?
Show hintHide hint
Consider how this could make calculations easier.
3Question 3.
Which of the following is a critical assumption when analyzing industrial waste?
- A) No evaporation occurs
- B) Total solid remains constant
- C) All organic matter is lost
Show hintHide hint
Think about which factor would complicate analysis.

- True
- False
Show hintHide hint
Consider what happens to solids in a mixed system.
Question 5.
You're tasked with recalculating the concentration of a chemical in a mixed sludge after adding specific volumes of both contaminated and unpolluted rainwater. What steps do you take?
Show hintHide hint
Consider how the different volumes impact total concentration.
Question 6.
Given a scenario where evaporation cannot be ignored, re-evaluate how this alters your mass balance equations and assumptions.
Show hintHide hint
Draw a flow diagram to visualize mass loss.
