ABOUT THE BOOK
Heat Transfer is the study of thermal energy moving from one location to another because of a temperature difference. It connects thermodynamics with real equipment such as heat exchangers, boilers, condensers, furnaces, cooling systems, pipelines, engines, electronic devices, and industrial process plants.
This book presents heat transfer in a practical engineering sequence. It begins with the three fundamental modes—conduction, convection, and radiation—and then develops resistance networks, extended surfaces, transient conduction, boiling and condensation, heat exchangers, pipe heat transfer, and industrial applications.
Special attention is given to formulas, units, assumptions, numerical examples, design thinking, troubleshooting, and practical interpretation. The objective is to help a student move from 'I know the equation' to 'I know when and why to use the equation.'

ABOUT THE AUTHOR
Chetan Singh Chauhan is an engineering professional with experience in industrial electrical and maintenance operations. His professional work has involved preventive maintenance, critical spare management, motors, transformers, MCCs, rotating equipment, documentation, energy management, 5S activities, and practical plant problem-solving.
His approach to technical writing is strongly application-oriented: concepts are introduced in simple language, followed by equations, examples, engineering interpretation, and practical observations. This style is intended to help students, technicians, supervisors, and engineers connect classroom theory with industrial equipment.
The author has academic and professional interests spanning electrical engineering, operations management, maintenance engineering, industrial systems, and practical technical education.
Author's learning philosophy
A strong engineer should be able to explain a principle, select an appropriate model, perform a calculation, check whether the result is physically reasonable, and communicate the conclusion clearly. This book follows that philosophy throughout.
