Studies of combustion can achieve this condition with jets in a design of Jack Longwell’s. For 10 points each:
[10m] Name this condition that holds when residence time is relatively large and allows a constant concentration to be assumed. In a plug flow reactor, this condition only holds in the radial direction.
ANSWER: perfectly mixed [accept well-mixed; prompt on continuously stirred]
[10e] The cross-sectional velocity profile of a laminar flow reactor has this shape because the velocity is a quadratic function of distance from the wall.
ANSWER: parabola [or parabolic]
[10h] This technique takes advantage of the flat profile of electro-osmotic flow to preconcentrate samples before capillary electrophoresis. This technique focuses analytes into discrete peaks by sandwiching them between buffers with different mobilities.
ANSWER: sample stacking [or word forms of stacked; accept isotachophoresis or ITP]
