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