The presented classification, however, is not absolutely fixed by the fluidic setup because single-droplet generators can even change categories when being operated in different modes. For example, a device of the pressure or flow boundary condition class can convert to the combined pressure and flow boundary condition class or vice versa. [Pg.647]

Figure 3-13 shows the classification of gas movers into two broad categories, based primarily on maximum discharge pressures. The pressure ratio of a fan (absolute discharge pressure to absolute suction pressure) is less than 1.2. The... [Pg.122]
