Retention time in a liquid-liquid vessel

Input(s)

$\mu$: Viscosity of Predominant Phase $(\mathrm{cP})$

A: Separator Constant - varies from 0.05 to 1.0 (dimensionless)

$\gamma_{\mathrm{b}}$: Specific Gravity of Bottom Phase (dimensionless)

$\gamma_{\mathrm{t}}$: Specific Gravity of Top Phase (dimensionless)

Output(s)

$\mathrm{T}$: Retention Time $(\mathrm{h})$

Formula(s)

$$ \mathrm{T}=\frac{\mathrm{A} * \mu}{\gamma_{\mathrm{b}}-\gamma_{\mathrm{t}}} $$
