Using Gaussian dispersion equations, the stability class, and dispersion coefficient data for a source emitting SO2 at a rate of 50 g/sec on a very sunny summer day with a wind speed at anemometer height of 2.9 m/sec, and effective stack height of 30 m at temperature = 293K, determine the stability class and dispersion coefficients for receptor distances of 200, 500, 800 m and 1000 m. Calculate and draw the ground level concentrations in ppbv as a function of distance (T=20 Celsius and P =1atm). The wind exponential coefficient = 0.2. ANSWER: Class B

Expert Solution

Ans- The stability class of the Gaussian dispersion is given by the solar condition and the velocity of the wind the stability chart is given here

1. For wind speed from the above chart it is clear that the stability class is B for the wind speed of 2.9 and strong sunny day.

Using the data from 15 automobile accidents, the correlation coefficient between the combined speeds of the cars (x) in an accident and the amount of damage done (y) is 0.7831. The regression equation for the two variables is y = 801.518 + 162.845x. a. Is this a significant correlation? b. If the answer to last part is YES, then predict the amount of damage done in an accident in which the combined speeds of the car involved was 100 mph.
