<p>The device has a set of flow surfaces (23) that is occupied by flowing fluid. The flow surfaces are extended between a fluid inlet area i.e. slot (10), and a concentric fluid outlet area. A wall (26) is attached to the flow surfaces, where the wall is extended over the flow surfaces, and the wall is provided with an upper side (28) for overflowing fluid. A vent unit (24) separates the overflowing fluid from the flow surfaces through the wall, where the device is in circular form. An independent claim is also included for a method for creation of hydraulic projection.</p> |
