Aren't there always shear forces (if that's the correct term) involved in stirring a liquid, since the parts farther from the stirrer lag behind the closer bits?
Well, I dunno. Again, a cup of water with a spoon in it that's been frozen can still be "stirred" - or at least undergo the same motion as stirring.

This would lead one to suggest that it is possible to stir a cylinder of water with theoretically zero mxing forces.

You would get sedimentation in the nodes.
I would think so... Excellent.

Could it be that for a stirred glass, the centre acts as a node? :shy:
