Volume of dilution water or mud required to maintain circulating volume
Input(s)
\(\mathrm{V}_{\mathrm{m}}\): Volume of Mud in Circulating System (bbl)
\(\mathrm{F}_{1}: \quad \%\) Low Gravity Solids in System (%)
\(\mathrm{F}_{\mathrm{o}}: \quad \%\) Optimum Low Gravity Solids Desired (%)
\(\mathrm{F}_{\mathrm{a}}: \quad \%\) Low Gravity Solids Added (%)
Output(s)
\(\mathrm{V}_{\mathrm{wm}}\): Volume of Dilution Water or Mud Required (bbl)
Formula(s)
\[
\mathrm{V}_{\mathrm{wm}}=\frac{\mathrm{V}_{\mathrm{m}} *\left(\mathrm{~F}_{1}-\mathrm{F}_{\mathrm{o}}\right)}{\mathrm{F}_{1}-\mathrm{F}_{\mathrm{a}}}
\]
