A trash incinerator has an effective stack height of 100 m. On a sunny day with a 2 m's wind the concentration of sulfur dioxide 200 m directly downwind is measured at 5.0 X 10⁻⁵ g/m³. Estimate the mass release rate (in g/s) of sulfur dioxide from this stack. Also estimate the maximum sulfur dioxide concentration expected on the ground and its location downwind from the stack.
