The water jet pump has two entry pipes and one exit, and consists, in principle, of two pipes one inside the other. At the water entry a water jet shoots under full pressure out of a nozzle into a slightly larger pipe. The water jet thereby carries away air or fluid from the second entry. <br> This is caused by the negative pressure in a drifting fluid, and thus it is an application of the hydrodynamic paradox (objects close to drifting fluids are aspirated instead of being pushed away).
