Air pollution control engineering third edition pdf

HW 1 Chapters 1 through 3 1 Comment on Example 1.1 and Problem 1.5 in textbook. Another “solution” proposed for Los Angeles was to dissipate the inversion layer by spraying water into it, evaporating the water and thus cooling the warm inversion layer to promote better vertical circulation. Estimate the amount of water (in gallons) required to cool a 500-ft-thick layer of air covering the 2400-square-mile basin by 5.0 °F. 2 Explain what’s meant by (a) primary and (b) secondary particulate. Which one do you think tends to be finer (smaller)? Why? 3 Refer to problem 2.2 in the text. Assume a density of 2 grams per cubic centimeter. 4 Refer to problem 2.8 in the text. Do parts a) and b); in part c), differentiate to show that Δ​L​v​ / ​L​v​ ​ = - Δ​c ​/ ​c 5 This problem involves monitoring data that you’ll use at different times during the semester. Go to this website ​and select PM10, 1995-2005, Kansas City, MO-KS, and “all sites.” Once the plots are made, download the data as a CSV file (using the link at the bottom of the page). BE SURE TO SAVE THE FILE BECAUSE WE’LL USE IT THROUGHOUT THE SEMESTER. 6 This ​site​ contains historic ambient air quality standards for particulate matter (PM). What’s the difference between a “primary” and a “secondary” standard? Compared to the other criteria pollutants, PM has had major revisions to not only the numerical standards, but also in the basis (e.g., TSP, PM10, PM2.5) for the standard. Why do you think that’s the case? 7 Do problem 3.1 in the text. (I believe that the answer in the back of the book is incorrect.) 8 Refer to problem 3.2 in the text. What is the allowable emission factor in terms of lb/ton? 9 Suppose a power plant burns 3000 tons of coal per day, with the coal having an ash content of 4%. The split between bottom and fly ash is 30/70. The local regulatory agency has permitted the plant for a maximum PM emission rate of 2 g/s. What control efficiency is necessary? ...
