Height of downcomer filling

Input(s)

$\mathrm{h}_{\mathrm{c}}$: Clear Liquid Height (in.)

$h_{\mathrm{e}}$: Dry Tray Height (in.)

$\mathrm{h}_{\mathrm{u}}$: Head Loss Under Downcomer (in.)

$\rho_{1}$: Liquid Density $(\mathrm{g} / \mathrm{cc})$

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

$\mathrm{h}_{\mathrm{i}}$: Tray Inlet Head (in.)

Output(s)

$\mathrm{h}_{\mathrm{d}}$: Height of Downcomer Filling (in.)

Formula(s)

$$ \mathrm{h}_{\mathrm{d}}=\left(\mathrm{h}_{\mathrm{c}}+\mathrm{h}_{\mathrm{e}}+\mathrm{h}_{\mathrm{u}}\right) *\left(\frac{\rho_{\mathrm{l}}}{\rho_{\mathrm{l}}-\rho_{\mathrm{g}}}\right)+\mathrm{h}_{\mathrm{i}}+1 $$
