4. A point source Gaussian plume model for a power plant uses 50 m as the effective stack height (see Figure P7.32). The night is overcast. (Note: This is not the same as "cloudy" in this model; check the footnotes in Table 7.8.) Your concern is with ground-level pollution at two locations, A and B, which are 1.2 and 1.4 km directly downwind from the stack. a. At what distance will the maximum concentration of pollution occur? Which location (A or B) would have the higher level of pollution? b. suppose the sky clears up, and the windspeed stays less than 5 m/s. Will the location downwind at which the maximum concentration occurs move? If so, will it move closer to the stack or further away from the stack? (H remains 50m) c. Under the new conditions in part b, which house would experience the most pollution? 4.
