Challenge Problems

Push your limits with challenges.

Question 1

A factory emits pollutants with a known emission rate of 100 kg/hr at a height of 30 meters. Given the average wind speed at this height is 5 m/s and the atmospheric conditions are stable (Class D), calculate Sigma Y and Sigma Z.

💡 Hint: Remember to use the stability class chart as a guide!

Question 2

You are tasked with designing an environmental study to measure pollutant dispersion around an urban area. Outline the steps you would take to ensure accurate wind speed and stability measurements.

💡 Hint: Consider how you might categorize different environmental conditions affecting your measurements.
