Mechanical Engineering 200: Thermodynamics I

This class introduces the basics of engineering thermodynamics. It discusses the relationships between temperature, pressure, density, energy, entropy, work, heat transfer, and mass transfer. The class uses three laws of physics: conservation of energy, conservation of mass, and increase of entropy. It introduces a small set of components — nozzles, diffusers, pumps, compressors, turbines, throttles, and heat exchangers — and shows how they combine to form power plants, refrigerators, air conditioners, heat pumps, automobile engines, jet engines, and other useful machines. The class analyzes these machines and derives fundamental limits on their performance.
