Dispersivity Calculator The dispersivity equations are
based on a characteristic length, L. This length is calculated based on
the nominal plume radius. To evaluate the radius, enter the injection
rate, duration of injection, formation porosity and formation thickness.
From these data, a piston displacement cylinder is calculated. Using the
radius of that cylinder and a dispersivity of 150 ft, the characteristic length
is calculated assuming the edge of the plume is defined by the 1 x 10-9
normalized isoconcentration line.
