Main Question or Discussion Point
I am looking for help on how to determine sedimentation differences of particles of different densities in a aqueous environment. Will particles of different densities sediment at different speeds, and how can that be calculated. Anotherwords something with a denisty of less that one will clearly float up, while higher densities objects will sink until they hit the bottom. Is there way to determine their speed of movement and how it would change with changes in relative gravity. I suppose at 0 gravity a life preserver will not float and rock will not sink. Thanks in advance for your help.
