HOMEWORK I (DUE ON Feb 08) 1. H 2 S is vented from a stack which has an effective height of 50 m. The wind speed is 2.5 m/s on an overcast night. For an emission rate of 0.06 g/s, determine the maximum ground-level concentration on the plume center line downwind from the stack. If the odor threshold for H 2 S is 0.00047 ppm, plot the region which an average person could detect H 2 S by smell. (10%) 2. A ground-level source (H = 0) is emitting pollutants at an unknown rate. At 1 km directly downwind of the source, the measured ground-level concentration of the pollutant is 10 μ g/m 3 . The stability category is A. Estimate the emission rate of this source. (5%) 3. A power plant is emitting its stack gas from a 50-m high stack. For its conditions, the plume rise is given by where us is the wind speed in m/s. The stability category is C. At what speed will the maximum calculated ground-level concentration occur? Hint: This requires a trial-and-error solution. (10%) 4.
