==Continuous Stirred-Tank Reactor==
A ''continuous stirred-tank reactor'' ('''CSTR''') is a well mixed tank with a flow of material flowing both into and out of it.
===Design Equation===
Like a batch reactor, CSTRs can be assumed to be well mixed. Additionally, CSTRs are almost always run at [[steady state]], thus the differential term of the design equation is 0. The design equation for a CSTR is
:F<sub>j0</sub> - F<sub>j</sub> + r<sub>j</sub>V = 0
Since the well mixed assumption means that conditions anywhere in the tank are equal to conditions at the exit, r<sub>j</sub> is evaluated at the conditions of the exit stream.
