amount of water, various type of water mist systems and nozzles have been developed so far, where the water pressure is increased and the orifice diameter is decreased by an order of magnitude. It would be advantageous to form a spray with fine droplets, although not necessarily as small as those produced by a typical water mist system, without .

TECHNICAL REFERENCE TABLE OF CONTENTS - spray

the effective spray angle varies with spray distance. Liquids more viscous than water form relatively smaller spray angles (or even a solid stream), depending upon viscosity, nozzle capacity and spraying pressure. Liquids with surface tensions lower than water will produce relatively wider spray angles than those listed for water.

A water spray system is connected to the supply through an automatically or manually actuated flow control valve. Water is then piped to specially designed nozzles which distribute it over the protected area. Automatic valves are actuated by a detection device installed in the protected area. Types of system The two types of water spray system are: 1.

Spray nozzle - Wikipedia

A spray nozzle is a precision device that facilitates dispersion of liquid into a spray. Nozzles are used for three purposes: to distribute a liquid over an area, to increase liquid surface area, and create impact force on a solid surface. A wide variety of spray nozzle applications use a number of spray characteristics to describe the spray.

The size of the spray particle is important because it affects both efficacy and spray drift of the application of an herbicide, insecticide, or fungicide. If the size of the spray particle (for example, 250–500 microns) is doubled and the application volume stays the same, you have only one-eighth as many spray droplets (Figure 1).
