Reply to comment by colcob in If I had two cups of water, one normal size and one as big as a swimming pool and stirred them both with proportionally sized spoons, would the larger pool of water keep spiraling longer than the smaller? by r3volc
Another factor in favour of the big pool: at the same rotational rate, the big pool will have less shear because the difference in speed between two points a given distance apart is smaller than the same two points in the small cup, so I would imagine less energy would be lost to turbulence
