1. A stack emitting 80 g/s of NO has an effective stack height of 100 m. The wind speed is 4 m/s at 10 m, and it is a clear summer day with the sun nearly overhead (i.e stability class B). a) Estimate the ground level NO concentration b) Estimate concentration directly downwind at a distance of 2 km c) Estimate the concentration at the point downwind where NO is maximum d) Estimate concentration at a point located 2 km down wind and 0.1 km off the downwind axis 2. A long line of agricultural waste emits 0.3 g/s-s of particulate matter on a clear fall afternoon with winds blowing 3 m/s perpendicular to the line. Estimate the ground level particulate concentration 400 m downwind from the line.

A stack emitting 80 g/s of NO has an effective stack height of 100 m. The
wind speed is 4 m/s at 10 m, and it is a clear summer day with the sun
nearly overhead (i.e stability class B).
a) Estimate the ground level NO concentration
b)
Estimate concentration directly downwind at a distance of 2 km
c) Estimate the concentration at the point downwind where NO is maximum
d) Estimate concentration at a point located 2 km down wind and 0.1 km off
the downwind axis
2. A long line of agricultural waste emits 0.3 g/s-s of particulate matter on a
clear fall afternoon with winds blowing 3 m/s perpendicular to the line.
Estimate the ground level particulate concentration 400 m downwind from
the line.
