  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 a 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 the regions of shock compressed flow. The outflow rate is
directly related to the compression ratio of the gas at the shocks. These
estimated rates roughly match the rates in real observations as well as those
obtained from numerical experiments. In special geometries, where the solid
angle of the outflow is higher, the disk evacuation takes place creating
quiescence states. Outflows are shown to be important in deciding the spectral
states and Quasi Periodic Oscillations (QPO)s of observed X-rays.
