Settling Stokes s diameter Drag diameter Free-fall diameter... [Pg.52]

At a low Re3uiolds number, the drag diameter equals the surface diameter of convex particles. For this case, the Stokes diameter, defined as the free-fall diameter in the laminar flow region, is related to sphericity as follows ... [Pg.59]

T] = 0.00125 Pa s. Alternatively, for comparison purposes, a size frequency distribution may be plotted or tabulated against free-falling diameter. [Pg.350]

A photosedimentometer has also been described for measuring free-falling diameters up to 20 cm in size with an application using coke. The system has been used to accurately measure a range of materials [31 ]. [Pg.373]

If the powder is initially concentrated in a thin layer floating on the top of a suspending fluid, the size distribution may be determined by plotting the fractional weight settled against the free falling diameter. [Pg.388]

Cumulative Methods. In cumulative methods the settling rate of suspensions or free-falling diameter are monitored. Cumulative methods have an advantage over incremental methods in that the amount of sample required is small (about 0.5 g), which reduces interaction between... [Pg.96]

The free-falling diameter, d, is the diameter of a sphere having the same density and the same free-falling velocity (or terminal velocity) as the particle in a fluid of same density and viscosity. In the Stokes law region, the free-falling diameter is the Stokes diameter defined earlier. [Pg.13]
