A spray apparatus includes a body having an outer surface and an interior portion, and a first nozzle (30) arranged in the interior portion of the body. The first nozzle (30) includes a first material inlet, a first convergent region (53), a first throat region (55), a first divergent region (57), and a first outlet (10). The first throat region (55) and first outlet (10) establish a first expansion ratio. A second nozzle is arranged in the interior portion of the body adjacent the first nozzle (30). The second nozzle (31) includes a second material inlet, a second convergent region, a second throat region (92), a second divergent region, and a second outlet. The second throat region (92) and the second outlet establish a second expansion ratio that is distinct from the first expansion ratio.
