41.
A suspension of glass beads in ethylene glycol has a hindered settling velocity of 1.7 mm/s, while the terminal settling velocity of a single glass bead in ethylene glycol is 17 mm/s. If the Richardson-Zaki hindered settling index is 4.5, the volume fraction of solids in the suspension is

Uc/Uo = E^4.5
1.7/17= E^4.5
0.1=E^4.5
log 0.1= 4.5 logE
-1=log E
antilog -1= E
E =0.6
1.7/17= E^4.5
0.1=E^4.5
log 0.1= 4.5 logE
-1=log E
antilog -1= E
E =0.6
