Terminal Settling Velocity
Calculate the settling velocity of the solids, adjusted for solids concentration. Use these equations to obtain the basic velocity [10]:
(16-17)ws=(A+
B
S∗
)−1
√
(s−1)gdN
Where:
S∗=
dN
4v
√
(s−1)gdN
ws = settling velocity, cm/s or ft/s
A,B = coefficients dependent on particle shape factor and roundness (see Table 16-10)
