COURSE OBJECTIVES: This course introduces introductory level materials in engineering thermodynamics to all majors of engineering students. It offers following topics –thermodynamic concepts (10 %); properties of substances state and phases; conservation principles and the first law of thermodynamics; entropy and the second law of thermodynamics; system analysis using the second law of thermodynamics, basis of vapor power plants, gas power systems and refrigeration/heat pump systems. Students learn fundamental concepts and how to use them for solving real-world engineering problems. A combination of visual demonstration, problem solutions and conceptual design approaches for engineering thermodynamic systems is used for enhancing fundamental understanding and engineering applications. Issues of communication skills and contemporary problems are also discussed.

In this course you will learn principles of energy transfer by heat in more details. In particular, the following questions will be answered: What is heat transfer? How is heat transferred? Why is it important? One objective is to develop an appreciation for the fundamental concepts and principles that underlie heat transfer processes. A second objective is to illustrate the manner in which a knowledge of heat transfer may be used with the first law of thermodynamics (conservation of energy) to solve problems relevant to technology and society. You will develop an intuitive understanding of heat transfer by using the physics and physical arguments that underpin the theory.
