Thermodynamics is an engineering science that is central to most mechanical engineering applications. This course provides an introduction to the thermodynamic concepts that will be required in following courses and in professional applications. The course provides a background for understanding how energy systems such as engines and refrigerators operate.


CLO-1: Apply the first law of thermodynamics to closed systems and compute the thermodynamic properties of fluids. (C3)
CLO-2: Analyze the thermodynamics processes for open and closed system and retrieve the required properties.(C4)
CLO-3: Analyze the performance of power and refrigeration cycles by applying the second law of thermodynamics and concept of entropy. (C4)
