The formula to calculate the Percent Solids in Slurry is:
\[ PSS = \frac{MS}{MSL} \times 100 \]
Where:
A percent solids in a slurry is the ratio of the mass of solids to the mass of an entire slurry solution.
Let's say you have a mass of solids (MS) of 20 kg and a mass of slurry (MSL) of 100 kg. Using the formula:
\[ PSS = \frac{20}{100} \times 100 = 20 \% \]
So, the percent solids in the slurry (PSS) would be 20%.
