Concentration of solids in slurry:
Many metallurgical processes have feed and/or product streams that consist of mixtures of solids and liquids. These mixtures are called slurries.
The relationship between wt % solid (%x) and specific gravity of solid phase ( ) and that of slurry
( ) when water is used as a medium can be obtained:
Volume of slurry = Volume of solid + Volume of water. Consider 1 kg slurry with %x as solids weight percent, then

Mass flow rate of dry solid in slurry (M)

F is volume flow rate in m3/hr.

Conclusion
In this lecture the units and dimensions of physical quantities are derived from fundamental unit of mass, length, temperature and time. Suitable examples are given to illustrate the derivation of units.
