PrefaceOBJECTIVESHeat transfer is a basic science that deals with the rate of transfer of thermal energy. This introductory text is intended for use i heat and mass transfr by cengel in a first course in heat transfer for undergraduate engineering students, and as a reference book for practicing engineers. The objectives of this text are• To cover the basic principles of heat transfer.• To present a wealth of real-world engineering applications to give students a feel for engine heat and mass transfr by cengel ering practice.• To develop an intuitive understanding of the subject matter by emphasizing the physics and physical arguments.Students arc assumed toheat and mass transfr by cengel
