Vapor mass velocity of tray type tower

Input(s)

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

$\rho_{1}$: Liquid Density $\left(\mathrm{lbm} / \mathrm{ft}^{3}\right)$

$\rho_{\mathrm{g}}$: Gas Density $\left(\mathrm{lbm} / \mathrm{ft}^{3}\right)$

Output(s)

w: Vapor Mass Velocity $\left(\mathrm{lbm} / \mathrm{h} \mathrm{ft}{ }^{2}\right)$

Formula(s)

$$ \mathrm{w}=3600 * \mathrm{~K}_{\mathrm{s}} *\left(\left(\rho_{\mathrm{l}}-\rho_{\mathrm{g}}\right) * \rho_{\mathrm{g}}\right)^{0.5} $$
