Use a spreadsheet program to determine the location of a ground isopleth for a plume. The spreadsheet should have specific cell inputs for release rate (g/s), release height (m), spatial increment (m), wind speed (m/s), molecular weight of the released material, temperature (K), pressure (atm), and isopleth concentration (ppm). The spreadsheet output should include, at each point downwind, both y and z dispersion coefficients (m), downwind centerline concentrations (ppm), and isopleth locations (m). The spreadsheet should also have cells providing the downwind distance, the total area of the plume, and the maximum width of the plume, all based on the isopleth values. Your submitted work should include a brief description of your method of solution, outputs from the spreadsheet, and plots of the isopleth locations.
Use the following two cases for computations, and assume worst-case stability conditions:
Case a: Release rate: 200 g/s
Release height: 0 m
Molecular weight: 100
Temperature: 298 K
Pressure: 1 atm
Isopleth concentration: 10 ppm
Case b: Same as above, but release height =10 m. Compare the plume width. area and downwind distance for each case. Comment on the difference between the two cases

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.
