A Continuous-Stirred Tank Reactor (CSTR) is a well-mixed vessel that operates at steady-state (Qin=Qout=Q). The main assumption in this case is that the concentration of the incoming fluid will become instantaneously equal to the outgoing upon entering the vessel. Fig. 2 explains visually this concept.
