Thermodynamic Cycles: Power and Refrigeration

This lecture covers thermodynamic cycles, focusing on power cycles like combustion engines and refrigeration cycles. It explains the energy balance, performance metrics like thermal efficiency, and the importance of temperature difference in energy transfer. The instructor discusses the concepts of conduction, convection, and radiation in heat transfer, along with their respective equations and applications in various states of matter. Examples and calculations are provided to illustrate the practical aspects of heat transfer and efficiency in mechanical, electrical, and combustion devices.
