1. 2. For an effective height of 150 m, an emission rate of 800 g/s, a wind speed of 8 m/s at stack height, and Class D stability. i- Calculate the downwind centerline ground-level concentrations at the following distances: 500, 1000, 2000, 4000, 7000, 10,000, and 15,000 m. ii- Draw the profile of the ground level concentration over the x-axis distance. iii- Draw the plume standard deviation variation in y-dierction. iv- Draw the plume stanadar deviation variation in z-dierction. V- Estimate the maximum downwind ground-level concentration (Cmax) and locate the distance at which it occurs (Xmax). The plan and profile views of a pollution source and surroundings are given below. For an emissions rate of 165.0 g/s, Class D stability, rough terrain, and a wind speed of 7 m/s (at 10 m), calculate the ground-level concentration at a receptor (A) that is 2002 m away from the source but not directly downwind (see diagrams). Assume plume rise is 50 m. T 100 m Stack Stack 2000 m Profile view u 2002 m Plan view A A 3. For a wind speed of 6 m/s, a stack gas exit velocity of 20 m/s, a stack diameter of 4 m, a heat emission rate of 15 MW, and an ambient pressure of 950 mbar, calculate the final plume rise in a natural atmosphere using (a) the Holland; (b) the modified Concawe; and (c) the Briggs method. Assume the stack gas has a molecular weight of 28.9 g/mole. Discuss the practical implication/meaning of the variation among these models. 4. Why the degree of nonlinearity is much less in the variation of y with distance for almost all the stability classes (Figure 19.7) in comparison to that of oz (Figure 19.8). Your answer should not be more than 4-5 lines. Note: Do not refer to Equations 19.4 and 19.5 or Table 19.2. 1. 2.
