Abstract: A showerhead engine internally swirls water within a swirling chamber. Multiple swirling chambers may be used, each separated from one another. The water is swirled angled through holes in a mid plate. As the water passes through the angled holes, it is projected out an angle. The water then contacts the swirling chamber wall and continues to follow the curvature of the wall. The curved wall paired with the angled entry causes the water to continue to swirl within the swirling chamber. The water is released out of the swirling chamber through slots, which allow the water to retain the angular velocity at a discharge angle.
