The turbomachine also includes a barrier disposed between the first and second chambers. The barrier is configured to separate the first fluid and the second fluid. Additionally, the barrier includes a first surface facing the first chamber and a second surface facing the second chamber. The turbomachine also includes an orifice extending from the first chamber to the second chamber. The orifice defines a fluid passageway. Additionally, the turbomachine includes a tube including a first end and a second end. The first end is coupled to the first surface and is disposed about a perimeter of the orifice. The tube is configured to at least partially contain the second fluid.
