(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a rigid sphere of radius R and density [tex]\rho[/tex]1 mooving (linearly) inside a liquid

of densiity [tex]\rho[/tex]0 and viscosity constant [tex]\mu[/tex]

the liquid is in hydrostatic equilibrium under gravitational field g.

what is the velocity of the sphere after a very long time assuming Raynolds constant is

very small?

2. Relevant equations

N-S equations

3. The attempt at a solution

my only problem is how should i deal with the sphere density [tex]\rho[/tex]1, can i ignored it?

since the density in N-S equations is the liquid density.

Thankes,

Omri
