a. What continuous release rate on the ground, in \(\mathrm{g} / \mathrm{s}\), of acrolein will result in a downwind concentration equal to \(0.05 \mathrm{ppm}\) located \(1500 \mathrm{~m}\) directly downwind on the ground? It is a bright sunny day with a \(3.5 \mathrm{~m} / \mathrm{s}\) wind speed. Assume rural conditions, a temperature of \(25^{\circ} \mathrm{C}\), and \(1 \mathrm{~atm}\) pressure. Where does the maximum concentration occur on the ground?

b. If the release now occurs \(10 \mathrm{~m}\) above ground level, what is the concentration \(1500 \mathrm{~m}\) directly downwind on the ground?

c. Where is the maximum concentration directly downwind (in \(\mathrm{m}\) ) for part (b) and what is its value (in ppm)?
