WebIt can be demonstrated that an infinite number of infinitely small CSTRs operating in series would be equivalent to a PFR. The behavior of a CSTR is often approximated or modeled by that of a Continuous Ideally Stirred-Tank Reactor (CISTR). All calculations performed with CISTRs assume perfect mixing.
