A disgruntled postal worker dumps a liquid culture of Anthrax into a river nine hundred meters upstream of the intake pipe for the municipal water works: 1011 organisms are introduced into the river which has a cross section of 0.6 m2 now determine what is the maximum concentration expected at the plant.If the river velocity is 40 cm/sec and the longitudinal dispersion coefficient is0.1 m2/ sec, and calculate how wide (2 standard deviations) is the cloud of organisms at the time peak concentration takes place at the intake pipe.
