  Outflows are common in many astrophysical systems which contain black holes
and neutron stars. Difference between stellar outflows and outflows from these
systems is that the outflows in these systems have to form out of the inflowing
material only. The inflowing material can form a hot and dense cloud
surrounding the compact object either because of centrifugal barrier or a
denser barrier due to pair plasma or pre-heating effects. This barrier behaves
like a stellar surface as far as the mass loss is concerned. We estimate the
outflow rate from such considerations. These estimated rates roughly match with
the rates in real observations as well as those obtained from numerical
experiments.
