We investigated flow in Schwarzschild metric , around a non-rotating black hole and obtained self-consistent accretion - ejection solution in full general relativity .
We covered the whole of parameter space in the advective regime to obtain shocked , as well as , shock-free accretion solution .
We computed the jet streamline using von - Zeipel surfaces and projected the jet equations of motion on to the streamline and solved them simultaneously with the accretion disc equations of motion .
We found that steady shock can not exist for \alpha \lower 2.15 pt \hbox { $ \buildrel > \over { \sim } $ } 0.06 in the general relativistic prescription , but is lower if mass - loss is considered too .
We showed that for fixed outer boundary , the shock moves closer to the horizon with increasing viscosity parameter .
The mass outflow rate increases as the shock moves closer to the black hole , but eventually decreases , maximizing at some intermediate value of shock location .
The jet terminal speed increases with stronger shocks , quantitatively speaking , the terminal speed of jets v _ { { j } \infty } > 0.1 if r _ { sh } < 20 r _ { g } .
The maximum of the outflow rate obtained in the general relativistic regime is less than 6 \% of the mass accretion rate .
