Scientific paper

Under the assumption that the broad emission line clouds in quasars are being driven outwards by radiative acceleration, one can use the Curtis Schmidt survey of Osmer and Smith to calculate the rate at which mass is being ejected from quasars. This is compared with the accretion rate derived from the luminosities of the quasars and the ratio of mass outflow to mass inflow is obtained. The author finds that typically ten percent of the mass which fuels a quasar is ejected in the form of broad line clouds, and discusses this in the context of a simple accretion disc model with outflow.
