The concentration of toluene at the stack is 100 ppm and the polluted air is emitted at 100 m3/minute. The density of toluene is about 0.9 g/mL. Pressure=1atm and temperature = 298K The stack height is 100m. The plume rise is 30 m. Estimate the down wind, centerline, ground-level concentration, at a down wind distance of 5000 meters from the stack. The atmospheric stability is class D, and the wind speed at a stack height is 5.0 m/s. ANSWER 0.54 ug/m3
