Force of the molecular, ionized, and X-ray phases of the outflow, Ṗ_out, in IRAS17, normalized to the source’s X-ray momentum rate, Ṗ_UFO (i.e., Ṗ_UFO/Ṗ_rad = 1.87 ± 0.62; see Longinotti et al. 2018), is shown as a function of the outflow velocities. The results for IRAS17 derived from NOEMA, MEGARA (i.e., Hα using n_e = 2500 cm⁻³), and XMM-Newton are shown with blue circles. To compare results across the three phases, we used the same formula for v_out as in Longinotti et al. (2023, i.e., Δv + 2 × σ_B) and normalized their Ṁ_out values assuming C = 1. Filled circles in orange and magenta represent the results derived for 2c component of the [OIII] emission (i.e., slow outflow) in the LR and MR setups, respectively. Two values are plotted for each setup (connected by a solid line), corresponding to the two assumed electron densities, n_e = 500 and 2500 cm⁻³ (see text for details). Empty circles, following the same color code as for the 2c component, indicate the 3c component of the [OIII] emission (i.e., fast outflow) in both setups. The fast [OIII] outflow is spatially resolved in the LR setup (empty orange circle), while it remains unresolved in the MR setup (empty magenta circles), for which we show the two results (lower limits) derived assuming the two n_e values. Results for three other well-known sources for which the energy-conserving regime has been observed, Mrk 231, IRAS 05189+2524, and IRAS11119+3257 (all ultraluminous infrared galaxies, shown using black, green, and red squares, respectively), are also included. Their data are extracted from Feruglio et al. (2015), Lutz et al. (2020), and Tombesi et al. (2015), respectively (see also Marasco et al. 2020 and references therein). The dashed blue and red lines represent the two linear fits marking the energy-conserving outflow regime: the former obtained using CO, Hα, and X-ray data, and the latter using these three points plus the [OIII] result from the LR-V setup (empty orange circle). The dotted gray line indicates the prediction for “momentum-conserving” outflows (i.e., Ṗ_out/Ṗ_UFO ∼ 1).
