The book "Mechanics of liquid and gas (cinematics of liquid, one-dimensional flow of gas)" by I. A. Verenich is a fascinating and deep immersion in the world of mechanics, which will become an indispensable assistant for students, graduate students and anyone interested in physics and engineering. In this work, the author masterfully combines theoretical aspects with practical examples, which allows the reader not only to assimilate the material, but also to see its application in real life. The book focuses on key aspects of fluid and gas mechanics, including fluid kinematics and one-dimensional gas flow. Verenich invites the reader to consider in detail the basic laws and principles that underlie these physical phenomena. It explains how liquids and gases behave under different conditions, what factors influence their motion, and how this knowledge can be applied in engineering tasks. The reader will be able to learn about important topics such as pressure, speed, viscosity and other characteristics that play a key role in understanding mechanics. This book will be of particular interest to engineering students, engineers, and anyone seeking to deepen their knowledge of physics and mechanics. If you study disciplines such as hydrodynamics, aerodynamics or continuum mechanics, Fluid and Gas Mechanics will be a valuable source of information and inspiration for you. In it you will find not only theoretical calculations, but also a lot of practical problems that will help to consolidate the knowledge gained. The topics raised in the book are of great importance for the modern world. An understanding of fluid and gas mechanics is necessary for the development of new technologies, the creation of efficient heating and ventilation systems, the design of ships and aircraft, as well as in the field of ecology and environmental protection. Verenic emphasizes the importance of taking these aspects into account in engineering practice, which makes his work relevant and in demand. The author's style is distinguished by clarity and accessibility of presentation. and . A. Verenich uses simple and understandable examples, which allows even complex concepts to be explained at an intuitive level. This makes the book not only a tutorial, but also a fascinating reading for anyone interested in physics. Verenich is also known for his other work in mechanics and physics, and his experience and knowledge is felt on every page. If you are looking for a book that will help you understand the intricacies of fluid and gas mechanics, then “Liquid and gas mechanics (liquid kinematics, one-dimensional gas flow)” will be an excellent choice. It will not only expand your knowledge, but also inspire further research and discoveries in this fascinating field of science. Do not miss the opportunity to immerse yourself in the world of physics and mechanics with this wonderful work!
