Challenge Problems
Push your limits with challenges.
Question 1
Given the emission rate of a toxic gas is 5 kg/hr and the wind speed is constant at 3 m/s, calculate the concentration at a certain distance downwind, considering a simple Gaussian dispersion model.
💡 Hint: Refer to the Gaussian dispersion equation - you will also need to consider dispersion coefficients.
Question 2
Analyze a scenario where pollutant concentration at a monitoring station deviates from predictions based on the mass balance model. Provide potential reasons for this discrepancy.
💡 Hint: Think about how variable external factors can disrupt stable conditions.
