Heat Transfer

ABOUT THE COURSE
Heat transfer occurs in many unit operations in variety of processes in chemical, petrochemical, power and pharmaceutical industries. Understanding the fundamentals governing heat transfer is key to designing equipment that involves heat exchange. This course for undergraduate students covers the fundamental aspects and quantitation of different modes of heat transport. The course can also serve as a refresher for graduate students

INTENDED AUDIENCE
Undergraduate and graduate students from Chemical and Mechanical Engineering, College teachers, Process engineers
