Consequently, replacing the pressure, p, by the effective pressure, [p.sub.*], and combining Equations (9), (11) and (140) to (142) the sedimentation velocity is expressed as:

Pollen is predicted to be dispersed farther under unstable conditions than neutral conditions, regardless of sedimentation velocity [ILLUSTRATION FOR FIGURE 1 OMITTED].
DEPOSITION VELOCITY, SEDIMENTATION VELOCITY, AND PARTICLE SIZE
where [U.sub.s] is the sedimentation velocity, [mu] is the fluid viscosity, [[rho].sub.p] is the density of the particle, [[rho].sub.f] is the density of the fluid, g is acceleration due to gravity or centrifugation, and R is the particle radius.
Positive or negative buoyancy force can introduce to a sedimentation velocity, which also scales as R2, like the DEP velocity of Equation (7).
