Hello Mechanical engineering students,
Applied thermodynamics is a core subject for Mechanical Engineering students in their second year B.Tech program. It deals with the study of energy transformation in various engineering systems such as engines, refrigeration systems, power plants, and air conditioning systems. The subject involves the application of thermodynamic principles, such as the laws of thermodynamics, to the design and analysis of such systems. Students learn about the thermodynamic properties of materials, heat transfer, combustion, and fluid mechanics. The study of applied thermodynamics is important for Mechanical Engineers as it helps them to understand the behavior of machines and systems, and to optimize their performance in terms of efficiency, power output, and environmental impact.
