Question: ( 2 0 points - Gaussian Plume ) A power plant stack has height of 5 0 m and diameter of 1 m . It

(20 points - Gaussian Plume) A power plant stack has height of 50m and diameter of 1m. It emits
75gs of NO at a temperature of 120C and a velocity of 15ms. The wind speed is 4ms at the
height of the stack, and it is a clear summer day with the sun nearly overhead. The ambient
temperature is 25C. Suppose a school is located 2km downwind. Estimate the ground-level NO
concentration at the school.
