The book "Collection of problems on technical thermodynamics and heat transfer" under the authorship of the famous scientist and teacher Markov is a unique resource for students, graduate students and everyone who is interested in the technical aspects of thermodynamics and heat transfer. This collection is not just a set of tasks, but a carefully thought-out tool that will help readers deepen their knowledge and skills in these complex, but extremely important areas of science and technology. Thermodynamics and heat transfer are fundamental disciplines that underpin many engineering solutions and technologies, from power systems to climate control. In his book, Markov offers readers a variety of tasks that cover a wide range of topics, ranging from the basics of thermodynamic processes to complex heat transfer issues in various environments. Each task is accompanied by detailed explanations and comments, which makes the material available even to those who are just starting their way in this area. This book will become an indispensable assistant for students of technical universities studying such disciplines as thermal physics, fluid mechanics and gases, as well as for engineers working in the field of design and operation of thermal engineering equipment. If you are passionate about engineering, physics or just want to expand your knowledge in the field of thermodynamics, this collection will be a real find for you. The topics raised in the book cover both classical aspects of thermodynamics and modern approaches to heat transfer. The author focuses on the practical application of theoretical knowledge, which allows readers not only to solve problems, but also to understand how these solutions can be used in real engineering projects. This makes the book especially valuable for those who seek to apply the theory in practice and want to be prepared for the challenges that may arise in their professional activities. Markov's style is distinguished by clarity and logical presentation. It skillfully combines theoretical aspects with practical examples, which allows the reader not only to remember information, but also to apply it in various situations. The author is also known for his other works in the field of thermodynamics and thermal physics, which confirms his deep knowledge and experience in this field. His books are often recommended by teachers and are used in educational institutions, which indicates a high level of confidence in his work. If you are looking for high-quality teaching material on thermodynamics and heat transfer, which will help you not only to prepare for exams, but also to understand how to apply the knowledge gained in real life, the "Collection of tasks in technical thermodynamics and heat transfer" will be an excellent choice. This book will not only expand your horizons, but also help you become more confident in your knowledge and skills. In conclusion, it is worth noting that the “Collection of tasks in technical thermodynamics and heat transfer” is not just a textbook, but a real find for anyone who wants to deepen their knowledge in the field of thermodynamics and heat transfer.
