hi friends

I am trying to model coaxial jet of water flowing into a water tank open to atmosphere. water level is maintained constant by allowing excess water to emerge out through an pipe at the top of the right wall of the tank. I am specifying velocity inlet at left wall of the tank.
what BC should be specified at free surface of water and tank outlet.

should i have to go for multiphase analysis, if yes what BC should i specify at the top and exit of the tank


thanks
