Assignment: Difference in Development of a Dispersion Formulation
I. What two physical phenomena account for the dispersal of pollutants in the atmosphere as a gas stream leaves a stack?
II. Why is a double-Gaussian format for a dispersion equation necessary in atmospheric studies?
III. What is the major difference in the development of a dispersion formulation for a ground source as opposed to an elevated source?
IV. What data are usually required to determine the maximum ground-level concentration?
V. What three sets of parameters control the phenomenon of a gaseous plume injected from a stack into the atmosphere?
VI. Most equations for predicting plume rise contain two terms that account for different physical reasons for the rise. What is the nature of these two terms?
VII. What is the general effect of sampling time on the expected concentration at a given location?
VIII. How does one modify the usual dispersion equation from a stack to account for the presence of an inversion trap?
IX. In what manner does one express the source emission rate for a line source such as cars along a highway?
X. How does one handle the change in concentration of a pollutant in air due to reaction and/or deposition with time?
