Another problem is if you define all inlet/outlets as pressure, the required mass flow rate cannot be obtained.

Similarly you cannot define all in terms of mass flow rate.

Iam working on a vortex tube(with 4 inlets).I wanted to know what are the boundary condtitions best-suited for analyzing a vortex tube? And what is the magnitude of the BC used?
