1. Introduction: Fundamentals Of Thermal Fluid Sciences Cengel
Thermal fluid sciences is a branch of engineering that deals with the transfer of heat and mass in fluids. It is a fundamental discipline in many engineering fields, such as mechanical engineering, chemical engineering, and aerospace engineering.
The book “Fundamentals of Thermal-Fluid Sciences” by Yunus A. Cengel provides a comprehensive overview of the fundamentals of thermal fluid sciences. The book covers a wide range of topics, including thermodynamics, fluid mechanics, and heat transfer.
2. Thermodynamics
Thermodynamics is the study of energy and its transformation. The first law of thermodynamics states that energy cannot be created or destroyed, but it can be transferred from one form to another. The second law of thermodynamics states that the entropy of an isolated system always increases.
Thermodynamics is used to analyze and design thermal systems and processes. For example, thermodynamics can be used to design a power plant or a refrigeration system.
