# Maximum recommended low-gravity solids

## Input(s)

SF: Maximum Recommended Solids Fractions (% by vol)

MW: Mud Weight (ppg)

## Output(s)

LGS: Maximum Recommended Lgs (% by vol)

## Formula(s)

\[
\operatorname{LGS}=\left(\left(\frac{\mathrm{SF}}{100}\right)-\left(0.3125 *\left(\left(\frac{\mathrm{MW}}{8.33}\right)-1\right)\right)\right) * 200
\]
