Discritization of the Gaussian plume model.

: In general a plume is more known than a puff for stack emissions. A plume may be regarded as a number of puffs ejected out in quick succession. Conversely a continuous plume can be discritized (dissected) at intervals to form puffs. The main objective of the present study is to establish a relationship between a plume and a puff by dissecting the plume longitudinally and equating the contents of the segmented plume to a spheroidal shaped puff for different distances and stabilities to meet vagaries of weather.
