Challenge Problems

Push your limits with challenges.

Question 1

A factory emits nitrogen oxides at a rate of 40 lbs/hr. If the emission factor for the process is 0.02 lbs pollutant per unit of activity (here the activity is 2000 units), calculate the emission rate. Would the emission rate change if the activity was doubled?

💡 Hint: Refer back to the relationships between emission factor and activity rate.

Question 2

Given a plume height of 50 meters with reflection considered, how can we mathematically illustrate the change at ground level concentration (using hypothetical numbers for concentration)?

💡 Hint: Remember the principles behind adding contributions from sources and using the equations presented.
