You can specify multiple outflow boundaries in Fluent. In the Outflow dialog box, set the Flow Rate Weighting to indicate what portion of the outflow is through the boundary. The Flow Rate Weighting is a weighting factor. See below for details on how to split the flow according to mass flow %:

Dear all,
I am simulating the laminar flow through a pipe having one(1) inlet and ten(10) outlets. As a boundary condition I am prescribing the inlet velocity for the inlet plane. For the outlets, I know the value of outflow discharges as a percentage of the inlet flow like

Inlet:100%       outlet1: 20%
                      outlet2:5%
                     outlet3:10%
                     outlet4:5%
                     outlet5:11%
.....
But, how to put this boundary condition in Fluent.
