I need to find out the rise rate of a spherical object (D=.02m) of SG 1.1 in a continous fluid of SG 1.5.
I was trying to use Fb(Buoyancy Force) - Fg(force of gravity) = Fd(drag force). I don't know which equation to use for the drag force term (with/without drag coefficient). Can anyone help please?

Thanks,

Sarah.

Sarah (Beth?):

Please don't clutter the Forum with double, identical posts. Not only is it confusing for responses, it also takes up space for no valid reason.

I am deleting your first post (signed "Beth") since both posts are exactly identical.

Drag on a sphere is calculated using stoke's equation, the above url gives more info.
