The volume of liquid passing through a nozzle (also called the nozzle’s capacity) is typically measured in liters per minute. Flow rate is affected by liquid pressure and other factors, including the specific gravity and viscosity of the liquid being sprayed.

Liquid Pressure

Spray nozzles are manufactured from a wide variety of materials that have been determined to meet the usual requirements of the applications most commonly associated with that type of nozzle. Standard materials include brass, steel, various stainless steels, hardened stainless steels, many plastics and various carbides. Spray nozzles can also be supplied in other materials upon special request. Materials of construction affect nozzle wear life and resistance to corrosion and abrasion.

Materials

Specific gravity is the ratio of the density of a fluid compared to the density of water. It must be considered to properly calculate flow rate. 

 **Alternatively**, if you don't know the specific gravity you may select the **Liquid Type** from a list of commonly-sprayed liquids and temperatures.

### Liquid Type

 The type of liquid sprayed and its temperature affects the specific gravity of the liquid and in turn affects the flow rate. The default liquid is water, with a specific gravity of 1.

Specific Gravity

The angle of the spray pattern as it emerges from the nozzle orifice, measured in degrees. Narrower spray angles provide less coverage of the sprayed surface. Wider spray angles provide greater coverage of the sprayed surface. Solid stream nozzles have a 0° spray angle.

Spray Angle

Different nozzle types are _**“rated”**_ at various pressures, depending on the function of the nozzle and the pressure at which a spray pattern is fully formed. The angle of the spray pattern as it emerges from the nozzle, when spraying at the rated pressure orifice, can serve as a reference point for comparing different nozzles.

Spray Angle at Rated Pressure

Model

A nozzle’s spray pattern is the shape the liquid forms after it emerges from the orifice. Nozzles are precision engineered to produce specific spray patterns such as full cone, flat spray, hollow cone and solid stream patterns. Different spray patterns are useful for different types of spray operations.
