Outlet BC with multiple outlets

I'll explain my problem:
I have to do a simulation in a pipe-like geometry with 1 inlet - where I set the velocity profile - and 4 outlet where I don't know neither velocity nor pressure.
So, at first I set pressure equal to 0 for all the 4 outlets and for velocity a pIOv condition. But the pressure condition is not realistic, because the outlets have differente sections and can't have the same pressure.
Then, I tried to set a pressure equal to 0 for 1 outlet and a zeroGradient condition for the other three outlets and the result was that the fluid exited only through the outlet with the p=0 condition while no flux was in the other 3 branches. And this is not realistic because it must be fluid in all the branches.
So, what could I try to make a realistic simulation with fluid in all the four branches?
