WATER SLURRY PROPERTIES
THOSE WORKING WITH WATER SLURRIES are interested in the solids specific gravity (S), the percent solids by weight (W), the specific gravity of the slurry mixture (M), and the percent solids by volume (V). The relationships are shown on the nomograph here, prepared prepared by F. F. Caplan, a
professional engineer, engineer, of Oakland, Calif. If any two properties are known, the other two are fixed. The nomograph gives a rapid simultaneous solution to the equations. Example: What are M and V if S = 2.5 and W = 62.5%? Align the S and W values and read M = 1.60 and V = 40%.
