The book is written by a group of authors who have been working together for many years. The book "Problems on Fundamentals of Hydraulics and Heat Engineering" is a comprehensive guide that covers the fundamental principles of hydraulics and heat engineering, providing readers with a deep understanding of the subject matter. The book is divided into four parts, each of which focuses on a specific aspect of hydraulics and heat engineering. The first part explores the basic concepts of fluid mechanics, including the laws of motion and the behavior of fluids under different conditions. The second part delves into the principles of heat transfer, including conduction, convection, and radiation, and their applications in various fields. The third part discusses the design and operation of heating, ventilation, and air conditioning (HVAC) systems, as well as the importance of energy conservation and efficiency in these systems. Finally, the fourth part examines the role of computer-aided design and analysis tools in modern hydraulic and heat engineering, highlighting their benefits and limitations. Throughout the book, the authors emphasize the need to study and understand the process of technology evolution, as it is essential for the survival of humanity and the unification of people in a warring state. They argue that by studying the history and development of technologies, we can gain valuable insights into how they have evolved over time and how they continue to shape our world today.
