Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with modeling pollutant dispersion for a local factory. If each emission is varying hourly based on demand, describe how you would approach choosing between steady-state and unsteady-state modeling.

💡 Hint: Focus on the dynamics of emitter variability in your reasoning.

Question 2

Develop a dispersion equation considering a pollutant with a steady emission rate of 500 kg/h under prevailing wind conditions of 2 m/s. Assume diffusion coefficients D_x, D_y, D_z.

💡 Hint: Integrate the emission rate and environmental conditions, applying relevant coefficients.
