Evaluation of hydrocyclone
Input(s)
MW: Average Density of discarded mud (ppg)
\(\mathrm{V}\): Volume of Slurry sample collected (quarts)
\(\mathrm{T}\): Time to collect slurry sample (s)
Output(s)
SF: Fraction percentage of solids (fraction)
MS: Mass rate of solids removed by one come of a hydroclone \((\mathrm{lb} / \mathrm{h})\)
WR: Volume of wate ejected by one cone of a hydroclone \((\mathrm{gal} / \mathrm{h})\)
Formula(s)
\[
\begin{gathered}
S F=\frac{M W-8.33}{13.37} \\
\mathrm{MS}=19530 * \mathrm{SF} * \frac{\mathrm{V}}{\mathrm{T}} \\
W R=900 *(1-S F) * \frac{V}{T}
\end{gathered}
\]
