Pressure Outlet boundary condition in OpenFOAM
 

Hi,

I am solving a problem to separate two immiscible liquids using a big settler tank which has one inlet at left (entrance for the dispersion to come in) and two outlets at right (one at top and other at bottom). I want to use pressure outlet BC at both outlets, but don't know how to set Pr. outlet BC in OpenFOAM. So, please some body help in this regard.
I know the inlet velocity of the dispersion.

Thanks,
dipsar...
