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)

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