A solid stream spray pattern is a solid stream jet formed through a machined orifice. The design of the inlet chamber maximizes the integrity of the solid stream to reduce disintegration of the jet. The addition of jet stabilizers help produce prolonged jet stream.
A flat fan spray pattern is formed when the liquid is distributed in an elliptical flat sheet. The tapered edges of the flat spray is useful when a number of nozzles are fitted to a spray bar. In this instance, nozzle spray pattern can be overlapped to produce and even spray distribution.
