# Mud weight reduction by dilution - Water/diesel/any liquid

## Input(s)

\(W_{2}\): Required mud density \((\mathrm{ppg})\)

\(W_{1}\): Initial Mud density (ppg)

\(V_{m}\): Initial Mud Volume (bbl)

\(D_{w}\): Water/Diesel density (ppg)

## Output(s)

\(V_{r}\): Required Volume of water/diesel/any liq (bbl)

## Formula(s)

\[
V_{r}=V_{m} * \frac{W_{1}-W_{2}}{W_{2}-D_{w}}
\]
