Conceptual Question Involving Fluids

  1. Apr 27, 2015 #1
    A sphere (with density less than that of water) is placed into 2 different cylinders. One with a spinning column of water and the other with a still column of water. Why does the sphere in the spinning column of water take much longer to float to the top of the cylinder?

    I was thinking about the sphere taking a larger trajectory thus experiencing more retarding force from the spinning column of water but is there anything else that I am missing?
