The first fluid is configured to receive a first fluid input. The second inlet is configured to receive a second fluid input. The nozzle includes a nozzle inlet positioned proximate the first inlet and a nozzle outlet positioned within the mixing chamber. The diffuser extends from the outlet and outward from the housing. The diffuser includes a diffuser inlet positioned within the mixing chamber.
