outflow BC for closed pipe (no inlet)
 
Hi folks, the problem is simple. But not sure what BC to use. Pipe with only outlet and no inlet. domain closed and mass is sucked out of the system at certain flowrate.

Since continuity cannot be used i use ideal gas.

But not sure what BC to give for the flowrate. Outflow/outlet vent/...?? i have the flow rate at the outlet.

Thanks in advance

Thanks.
