Table 2 Gas void fractions estimated using the VBE and pressure difference approach.
Gas location | Pressure difference method | VBE method | |||
|---|---|---|---|---|---|
Gas–water mixture height, h (ft) | Pressure difference, ΔPij (psi) | Gas fraction, \({\alpha }_{g}\) | Speed of sound, cm (ft/s) | Gas fraction, \({\alpha }_{g}\) | |
Between 487 and 2023Â ft | 740 | 22.42 | 0.06 | 1310 | 0.05 |
Between 2023 and 3502Â ft | 774 | 19.78 | 0.07 | 1680 | 0.06 |
Between 3502 and 5025Â ft | 1058 | 25.18 | 0.08 | 1750 | 0.07 |
