This course is on basic engineering thermodynamics. The first part, on single component systems, topics are basic concepts and definitions, conservation of mass, 1st and 2nd laws of thermodynamics for closed and open systems, thermodynamic properties of a pure substance and practical applications. The second part covers physical behaviour of a mixture of ideal gases, psychrometry, thermodynamics of reacting systems, combustion, phase and chemical equilibrium, and applications.Lecture notes will be provided and supplemented with assignments that emphasize systematic problem solving.
