Allowable gas velocity through gas separator

Input(s)

$K_{s}$: Empirical Gas Constant $(\mathrm{ft} / \mathrm{s})$

$\rho_{l}$: Liquid Density $(\mathrm{g} / \mathrm{cc})$

$\rho_{g}$: Gas Density $(\mathrm{g} / \mathrm{cc})$

Output(s)

v: Allowable Gas Velocity (ft/s)

Formula(s)

$$ \mathrm{v}=\mathrm{K}_{\mathrm{s}} *\left(\frac{\rho_{\mathrm{l}}-\rho_{\mathrm{g}}}{\rho_{\mathrm{g}}}\right)^{0.5} $$
