Among different grades of synthesized PAMs, PAM-[V.sub.3] exhibited highest settling velocity
Equation 3 indicates the settling velocity
(V) of a droplet with a density of [[rho].sub.w] and a radius of r, settling down in a bulk fuel with a viscosity of [mu] and a density of [[rho].sub.f], where g is the acceleration due to gravity.
After a juvenile drops off the fish host, the location where it comes to rest on the streambed should be determined by a combination of settling velocity
of the juvenile, current velocity (Fig.
The settling velocity
of sediment particles is one of the key variables in the study of sediment transport and is important in understanding suspension, deposition, mixing, and exchange processes.
in which ya is the thickness of the sheet-flow layer, Ca is the concentration at ya which equals the bed-load concentration, z*=[omega]/[kappa]u* is the suspension index, and [omega] is the particle settling velocity
. The similar expression of PDFM also can be created by the method below based on the Schmidt diffusion equation (Schmidt, 1925).
In the laminar flow regime, where Reynolds number  is approximately less than 0.1, the settling velocity
can be expressed by Stoke's law  in liquid Al during grain refinement that can be applied for the estimation of settling rate of metal droplets in the liquid slag .
To quantitatively study the particle motion, the time evolution of the vertical position (Y) and the settling velocity
([U.sub.y]) is shown in Figure 9 for Re = 10, 80, 100, and 200.
When the settling velocity
[omega] increases from 0.01 to 0.04 (Figure 2), the concentration profiles of different models exhibit more nonuniform distribution features.
[V.sub.s] is the settling velocity
After entrainment, the movement of pollen within large airflow patterns is generally considered in terms of the terminal settling velocity
of pollen grains (which depends on the density and the size of pollen grains) and on ambient meteorological conditions.
Droplet nuclei smaller than 5 [micro]m exhibit a settling velocity
below 1 m/h in still air, and can therefore follow the person's exhalation flows and the ambient air flows.
The change in settling velocity
of inertial particles in cellular flow was studied by Chan and Fung .
