Abstract
A laminar flow waterfall in the form of a single or multiple streams of water, each exiting from a nozzle in the top edge of a spa. The laminar water stream is created by a venturi nozzle located in a plenum chamber. The inlet side of the nozzle has a cover with a plurality of small holes forcing the water flow to enter the nozzle as laminar flow. A flow divider inside the venturi nozzle, from the inlet to the restriction of the nozzle, maintains the flow laminar through the nozzle. Light is injected into the flow divider at the inlet and is carried by the flow divider to be injected into the water flow at the restriction of the nozzle.
