<p>A self-powered nozzle assembly for use within a tank has a stationary body and a rotatable body rotatably connected to and in fluid communication with the stationary body. The rotatable body has an axis of rotation with at least one offset nozzle such that, as fluid is ejected from the at least one offset nozzle, the fluid applies a rotational force to the rotatable body. A rotational speed dampener is connected to the rotatable body.</p> |
