flow through the first mixer;
introducing a second flow of a low viscosity medium into
the convergent orifice for passage into the first mixer; and
directing media from the first mixer into a second mixer
having a plurality of static mixer elements disposed along a
longitudinal axis of the mixer and having a cross-sectional
flow area that is greater than the cross-sectional flow area
of the first mixer, wherein the cross-sectional flow area of
the second mixer is taken generally perpendicular to the
direction of flow through the second mixer.
21. A method of admixing at least two flowable media of
different viscosities, said method comprising the steps of
directing at least two flows of media of different
viscosities into a first mixer having a predetermined cross-
sectional flow area and a plurality of static mixers disposed
along a longitudinal axis for mixing therein, wherein said
cross-sectional flow area of the first mixer is taken
generally perpendicular to the direction of flow of the media
through the first mixer; and
thereafter passing the media from the first mixer into a
second mixer having a greater cross-sectional flow area than
said first mixer, wherein the cross-sectional flow area of the
second mixer is taken generally perpendicular to the direction
of flow
of the media through the second mixer, said second static
mixer having a plurality of static mixer elements disposed
along a longitudinal axis for mixing of the media therein.
22. A method of mixing first and second fluid media of
differing viscosities comprising the steps of
directing the media into a first mixer having a
predetermined cross-sectional flow area and a plurality of
