Hi richard!! If u use a mass flow rate at the outlet, you enforce the fluid to go out of your domain with a normal direction. If you use a pressure at the outlet, then your fluid are not going to be enforced to go out normally to the boundary limit. The BC could modify the velocity upstream the outlet.
