    Abstract: A nozzle includes a body having an entrance location and an exit location. The body has a curved exit surface defined at the exit location. An internal chamber is defined in the body below the curved exit surface and a channel extends between the entrance location and the internal chamber. A slit defines an opening in the curved exit surface. The slit extends from the curved exit surface into the internal chamber. The curved exit surface and the slit are configured to define a fanned spray when liquid flows out of the slit.
