Research creates rationale to interconnect existing bits of information which can help effective teaching while opening up new challenges for creative development. Research over the last several decades has expanded the knowledge base exponentially though it has not percolated into the curricula. Major thrust of chemical engineering education is to teach design and development of process equipment for performing unit operations and reactions. Process equipment are essentially multiphase contactors (and separators) with momentum, heat and mass transfer with or with out reactions between the different phases. Understanding multiphase flow through wide variety of process equipment is needed for rational design. It is interesting to note that all the chemical engineering operations and reactions are carried out in just four types of "units". A course is proposed to organize the vast body of knowledge in terms of "units" of chemical engineering operations.
