In engineering, heuristics are experience-based methods used to reduce the need for calculations pertaining to equipment size, performance, or operating conditions.
It is important to understand their limitations when applying them to different equipment and processes.
Only when failures have been investigated with conclusive results can remedial action be taken with confidence.
These heuristics were taken from Turton's "Analysis, Synthesis, and Design of Chemical Processes".
