This course will enable students to understand the basic concepts and principles of Heat and Mass Transfer. The course will highlight the analogies in the molecular and convective transport of heat and mass, thereby providing a unifying framework for appreciating transport phenomena principles. It also develops the necessary background that will prepare the student to apply the heat and mass transfer concepts in the design of industrial heat exchanger and separation processes equipment.
