ivanddd is on a distinguished road

I have small problem with boundary condition. I want to simulate flow through
pipe with some area and with pump (see fig). I know the mass flow rate through the pump, but I don't know what boundary conditions should I use at the input and at the output from the pipe. There is atmospheric pressure at the pipe input/output. I want to solve it in Fluent or maybe in OpenFOAM.

Thanks a lot for replay, Ivan :-)
