We present a detailed study of AGN feedback in the narrow-line region (NLR)of the Seyfert 1 galaxy NGC 4151. We illustrate the data and techniques neededto determine the mass outflow rate and kinetic luminosity of the outflowingionized gas as a function of position in the NLR. We find that the mass outflowrate peaks at a value of 3 solar masses per year at a distance of 70 pc fromthe central supermassive black hole (SMBH), which is about 10 times the outflowrate coming from inside 13 pc, and 230 times the mass accretion rate inferredfrom the bolometric luminosity of NGC 4151. Thus, most of the outflow mustarise from "in situ" acceleration of ambient gas throughout the NLR. Thekinetic luminosity peaks at 90 pc and drops rapidly thereafter, indicating thatmost of the kinetic energy is deposited within about 100 pc from the SMBH. Bothvalues exceed the mass outflow rate and kinetic luminosity determined for theUV/X-ray absorber outflows in NGC 4151, indicating the importance of NLRoutflows in providing feedback on scales where circumnuclear star formation andbulge growth occur.
