boundary conditions for a modified T-mixer
 

I have a problem with defining boundary conditions for a modified T-mixer system. In usual T-mixer systems the pumps are located on the inlet streams, so the inlet type is defined as velocity inlet and the outlet is defined as a pressure outlet or an outflow. In my system the pumps are located on one of the inlet streams and on the outlet stream. I could not find in fluent an option of velocity outlet or a pressure inlet. How can I define those boundary condition>?

u can use velocity inlet as the outlet, put a positive value to the velocity; and pressure inelt the same method
