A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe.

A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid . Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In nozzle velocity of fluid increases on the expense of its pressure energy.

Select the most appropriate primary nozzle is the most important, the following guidelines will help you determine what type and size of the nozzle is best for you.

There are five basic nozzle types:

The solid bore,the single gallonage (sometimes called variable pressure/variable flow), the adjustable gallonage,the automatic or constant pressure, Multi-Purpose Nozzle (combination solid bore and fog).

The main nozzle flow range

A nozzle cannot create flow. The accessible water, pump capacity, corrupt lays, etc., actuate what a nozzle can achieve. The arrangement needs to be analyzed to actuate what breeze ambit can be achieved. Actuate the best breeze amount that can be accomplished with accustomed engine pressures and corrupt lays. Actuate the minimum breeze that will be required. Consider whether the nozzle will consistently be acclimated on the aforementioned corrupt or whether it will be acclimated in added applications, which ability crave altered flows.

Flow control

The size of the orifice in the outlet of the nozzle controls the flow.Reaction force is determined by the GPM flow, nozzle pressure and pattern. First determine the maximum flow that can be controlled by the available manpower.

Nozzle pattern

Decide whether a solid bore nozzle or fog/straight beck nozzle is required. Superior fog nozzles aftermath about as acceptable a beeline beck as a solid bore nozzle but do crave a college basin pressure. The ability of a superior fog nozzle at 100psi is about the aforementioned as that of a solid bore nozzle or a multi-purpose nozzle at 50psi.

If the lower burden achievement of a solid bore nozzle accumulated with the patterns of a fog/straight beck nozzle would board your needs best, accede a multi-purpose or breach afar fog nozzle with the bunched solid bore tip. Fog nozzles are advised to accommodate a broadcast beck to assure personnel.

Teeth are provided to breach up the baptize into abate aerosol for bigger calefaction assimilation and beef effect. Spinning teeth accommodate accomplished breakdown of baptize for calefaction assimilation and beef conversion, due to the abolishment of fingering, which is abnormally important in LPG blazon fires.

Durable nozzle

Nozzles are designed to withstand reasonably tough service, but some nozzles will withstand more abuse than others. If durability is crucial and maintenance and repair opportunities are limited, a less complex nozzle design might be the best choice because the simplest nozzles are usually the toughest.
