• When liquid pressure drop <strong>in</strong>creases from 1.5 to 5 bars the droplet size<br />

decreases from 110 µm to 60 µm, the size of droplets grows from the spray<br />

center to its periphery whereas their velocity decreases.<br />

• Maximum liquid flux also shifts from the center of the spray to its<br />

periphery.<br />

• The spray angle <strong>in</strong>crease from 75 to 90 degrees with liquid pressure drop<br />

rise.<br />
