Translation Numbers and Methods of Determining Them . Methodical instructions for laboratory work" is a unique work created by a team of authors, which will become an indispensable assistant for students and specialists in the field of physics, chemistry and engineering sciences. It examines in detail the key aspects of transfer numbers - the most important parameters that determine the behavior of various substances in the process of their interaction. This publication not only enriches the theoretical base, but also offers practical recommendations that will help readers successfully cope with laboratory tasks. The book is intended for senior students of universities, graduate students and young professionals interested in thermodynamics, hydrodynamics and transfer processes. It will be useful to those who study physics and chemistry, as well as those who work in the development of new materials and technologies. If you are passionate about experimental science and want to deepen your knowledge of transfer numbers, this book will be a real find for you. One of the main topics raised in the book is the importance of transfer numbers in various scientific and engineering applications. Transfer numbers, such as the Reynolds number, the Peckle number, and the Nusselt number, play a key role in describing fluid and gas flows, heat transfer, and diffusion. Understanding these parameters allows us to predict the behavior of systems, which is critical when designing equipment and conducting experiments. The book offers the reader not only theoretical foundations, but also practical techniques, which makes it a valuable resource for laboratory work. The style of the authors is distinguished by clarity and accessibility of the presentation, which makes it easy to assimilate even the most complex concepts. They use many examples and illustrative illustrations, which makes the material more understandable and interesting. In addition, the book presents tasks and questions for self-examination, which will help to consolidate the material studied and prepare for practical exercises. The book "Numbers of transference and methods of their determination" is worthy of attention not only due to its content, but also due to the relevance of the topics it touches.
