Flow splitting at Comsol 6.2 Version

Hello Everyone,
I have a COMSOL Multiphysics geometry as shown in the figure below. The model consists of a main pipe with an inlet at the upstream end and an outlet at the downstream end.
The inlet flow rate is set to 40 L/h. At the first junction, where a U-shaped branch begins, I would like to split the flow such that half of the inlet flow rate is diverted into the U-shaped pipe (20 L/h).
Could you please advise how this flow split can be defined or enforced in COMSOL?
An image of the complete setup is also attached.

Hmm. If the geometry is made symmetric, the flow should split symmetrically. See attached figure.
