I need some help with this: I have a pool, with two inlets and two outlets. I know the mass flow at each inlet. I need to find the mass flow at each outlet. The pool is outdoor. My boundary conditions are mass flow at inlet, and static pressure at outlet (reference pressure: 0 bar, relative pressure: 1 bar, so I get atmospheric pressure). Is this OK? I'm making some mistake? Or it is more realistic if I use Average Static Pressure? Thanks for your help.

I think this is OK. But I do not know the situation downstream the outlets. Isn't there something limiting the flow?

Tip: Use a free slip wall for the topsurface.

Thank you very much for your answer and for the tip. About the situation downstream the outlets, there is nothing limiting the flow. The pool is discharging to an atmospheric tank.
