A spray apparatus includes a body having an outer surface and an interior portion, and a first nozzle arranged in the interior portion of the body. The first nozzle includes a first material inlet, a first convergent region, a first throat region, a first divergent region, and a first outlet. The first throat region and first outlet establish a first expansion ratio. A second nozzle is arranged in the interior portion of the body adjacent the first nozzle. The second nozzle includes a second material inlet, a second convergent region, a second throat region, a second divergent region, and a second outlet. The second throat region and the second outlet establish a second expansion ratio that is distinct from the first expansion ratio.
