If I draw only 1/4 of the real inlet of the pipe (I use periodic condition and I study only a "V" domain), I have to set 1/4 of the mass flow rate?

You are right.
I've not specified that I have 4 radial injection flows equally spaced, so I used a periodic boundary condition (and not symmetry)

I set periodic boundary conditions with 0 pressure gradient
