Assume the wind was blowing directly to the north, for the problem outlined in 9-30. use a spreadsheet and plot out the concentration at ground-level at a distance 1.5km directly downwind(north) from the stack starting from 500m east of centerline to 500 meters west of centerline in 50meter increments. (you are being asked to plot the concentration ground level in the “y” or transverse direction for z=0 and x=1.5 km). include the spreadsheet, an example calculation and the
