Homework Statement
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?
Homework Equations
N-S equations
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
