In fact, it is also related to disciplines like industrial engineering, and electrical engineering. While the emphasis is somewhat different in this book, the common material is presented and hopefully can be used by all. One can only admire the wonderful advances done by the previous geniuses who work in this field. In this book it is hoped to insert, what and when a certain model is suitable than other models. One of the difference in this book is the insertion of the introduction to multiphase flow. Clearly, multiphase is an advance topic. However, some minimal familiarity can be helpful for many engineers who have to deal with non pure single phase fluid. This book is the third book in the series of POTTO project books. POTTO project books are open content textbooks so everyone are welcome to joint in. The topic of fluid mechanics was chosen just to fill the introduction chapter to compressible flow. During the writing it became apparent that it should be a book in its own right. In writing the chapter on fluid statics, there was a realization that it is the best chapter written on this topic. It is hoped that the other chapters will be as good this one. This book is written in the spirit of my adviser and mentor E.R.G. Eckert. Eckert, aside from his research activity, wrote the book that brought a revolution in the education of the heat transfer. Up to Egret&#39;s book, the study of heat transfer was without any dimensional analysis. He wrote his book because he realized that the dimensional analysis utilized by him and his adviser (for the post doc), Ernst Schmidt, and their colleagues, must be taught in engineering classes. His book met strong criticism in which some called to &quot;burn&quot; his book. Today, however, there is no known place in world that does not teach according to Eckert&#39;s doctrine. It is assumed that the same kind of individual(s) who criticized Eckert&#39;s work will criticize this work. Indeed, the previous book, on compressible flow, met its opposition. For example, anonymous Wikipedia user name EMBaero claimed that the material in the book is plagiarizing, he just doesn&#39;t know from where and what. Maybe that was the reason that he felt that is okay to plagiarize the book on Wikipedia. These criticisms will not change the future or the success of the ideas in this work. As a wise person says &quot;don&#39;t tell me that it is wrong, show me what is wrong&quot;; this is the only reply. With all the above, it must be emphasized that this book is not expected to revolutionize the field but change some of the way things are taught. The book is organized into several chapters which, as a traditional textbook, deals with a basic introduction to the fluid properties and concepts (under construction). The second chapter deals with Thermodynamics. The third book chapter is a review of mechanics. The next topic is statics. When the Static Chapter was written, this author did not realize that so many new ideas will be inserted into this topic. As traditional texts in this field, ideal flow will be presented with the issue of added mass and added forces (under construction). The classic issue of turbulence (and stability) will be presented. An introduction to multi-phase flow, not a traditional topic, will be presented next (again under construction). The next two chapters will deal with open channel flow and gas dynamics. At this stage, dimensional analysis will be present (again under construction).</content> </entry> <entry> <id>86</id> <published>2018-09-07T17:21:42Z</published> <updated>2024-01-22T14:52:27Z</updated> <link rel="alternate" type="text/html" href="https://open.umn.edu/opentextbooks/textbooks/fundamentals-of-compressible-flow-mechanics"/> <title>Fundamentals of Compressible Flow Mechanics</title> <content type="html"><img alt="Read more about Fundamentals of Compressible Flow Mechanics" title="Fundamentals of Compressible Flow Mechanics cover image" class="cover " width="608" height="789" data-controller="common--cover" data-placeholder="/assets/common/placeholder-f8e123f91b7e13ad321132c609842fdd40121f691ee7db391b88763bc42be6a0.webp" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6MzMxMiwicHVyIjoiYmxvYl9pZCJ9fQ==--e8b8d3c077894fc156b3827bead6cabe65a5a3e1/Capture121.JPG" />This book deals with an introduction to the flow of compressible substances (gases). The main difference between compressible flow and almost incompressible flow is not the fact that compressibility has to be considered. Rather, the difference is in two phenomena that do not exist in incompressible flow. The first phenomenon is the very sharp discontinuity (jump) in the flow in properties. The second phenomenon is the choking of the flow. Choking is when downstream variations don&#39;t effect the flow. Though choking occurs in certain pipe flows in astronomy, there also are situations of choking in general (external) flow.</content> </entry> <entry> <id>645</id> <published>2018-12-08T23:23:46Z</published> <updated>2024-01-22T14:52:10Z</updated> <link rel="alternate" type="text/html" href="https://open.umn.edu/opentextbooks/textbooks/manufacturing-processes-4-5"/> <title>Manufacturing Processes 4-5</title> <content type="html"><img alt="Read more about Manufacturing Processes 4-5" title="Manufacturing Processes 4-5 cover image" class="cover " width="350" height="525" data-controller="common--cover" data-placeholder="/assets/common/placeholder-f8e123f91b7e13ad321132c609842fdd40121f691ee7db391b88763bc42be6a0.webp" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6NTgzLCJwdXIiOiJibG9iX2lkIn19--4d0cdd6b9539598920813a83a6b2b8da372ed13a/0000ManufaProc.jpg" />This textbook provides an introduction to the important area of manufacturing processes.

In addition, it describes steps that transforms un鈥搒table bodies to stable. This book is designed to replace all the other books and inseminate that recent developed technology and advances. The material in standard books is so entrenched, old, and outdated material that one can be only amazed. For example, concept like potential stability is not discussed or even mentioned in any of all the books that this author review. This book written from physical point of view rather then construction point of view like all the books review by this author on stability. It is hoped that the book could be used as a reference book for people who have at least some basics knowledge of science areas such as algebra, basic physics, etc. Even without deep understating the graphs in this book can be used to find necessarily quantities needed to understand if to fix your vessel.</content> </entry> <entry> <id>1035</id> <published>2021-08-16T04:00:34Z</published> <updated>2024-01-22T14:52:26Z</updated> <link rel="alternate" type="text/html" href="https://open.umn.edu/opentextbooks/textbooks/aerodynamics-and-aircraft-performance"/> <title>Aerodynamics and Aircraft Performance - 3rd edition</title> <content type="html"><img alt="Read more about Aerodynamics and Aircraft Performance - 3rd edition" title="Aerodynamics and Aircraft Performance - 3rd edition cover image" class="cover " width="685" height="1024" data-controller="common--cover" data-placeholder="/assets/common/placeholder-f8e123f91b7e13ad321132c609842fdd40121f691ee7db391b88763bc42be6a0.webp" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6MjczMSwicHVyIjoiYmxvYl9pZCJ9fQ==--c177a9fced79960cdc552be87dd5ebc83f46c010/A-AP-cover-PB-version-685x1024.png" />Aerodynamics and Aircraft Performance, 3rd edition is a college undergraduate-level introduction to aircraft aerodynamics and performance. This text is designed for a course in Aircraft Performance that is taught before the students have had any course in fluid mechanics, fluid dynamics, or aerodynamics. The text is meant to provide the essential information from these types of courses that is needed for teaching basic subsonic aircraft performance, and it is assumed that the students will learn the full story of aerodynamics in other, later courses. The text assumes that the students will have had a university level Physics sequence in which they will have been introduced to the most fundamental concepts of statics, dynamics, fluid mechanics, and basic conservation laws that are needed to understand the coverage that follows. It is also assumed that students will have completed first year university level calculus sequence plus a course in multi-variable calculus. Separate courses in engineering statics and dynamics are helpful but not necessary. Any student who takes a course using this text after completing courses in aerodynamics or fluid dynamics should find the chapters of this book covering those subjects an interesting review of the material. The 236-page text was created specifically for use by undergraduate students in Aerospace Engineering and was based on Professor Marchman鈥檚 many years of experience teaching related subject matter as well as his numerous wind tunnel research projects related to aircraft aerodynamics and his personal experience as the owner and pilot of a general aviation airplane. It has been used at Virginia Tech and other universities.

The material opens with describing the transformation of bits into digital baseband waveforms. Double-sideband suppressed carrier modulation and quadrature modulation then provide the foundation for the discussions of Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-ary Quadrature Amplitude Modulation (M-QAM), M-ary Phase Shift Keying (MPSK), and the basic theory of Orthogonal Frequency Division Multiplexing (OFDM). Traditional analog modulation systems are also described. Systems trade-offs, including link budgets, are emphasized. Interactive graphics allow the students to engage with and visualize communication systems concepts. Interactivity and in-line review questions enables students to rapidly examine system tradeoffs and design alternatives. The topics covered build upon each other culminating with an introduction to the implementation of OFDM transmitters and receivers, the ubiquitous technology used in WiFi, 4G and 5G communication systems.</content> </entry> <entry> <id>1047</id> <published>2021-08-29T07:07:05Z</published> <updated>2025-01-27T14:28:42Z</updated> <link rel="alternate" type="text/html" href="https://open.umn.edu/opentextbooks/textbooks/engineering-statics-open-and-interactive"/> <title>Engineering Statics: Open and Interactive</title> <content type="html"><img alt="Read more about Engineering Statics: Open and Interactive" title="Engineering Statics: Open and Interactive cover image" class="cover " width="404" height="509" data-controller="common--cover" data-placeholder="/assets/common/placeholder-f8e123f91b7e13ad321132c609842fdd40121f691ee7db391b88763bc42be6a0.webp" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6Mjc5MiwicHVyIjoiYmxvYl9pZCJ9fQ==--5444c8aebba7d4a49310aa02852f0f284ea42d2c/sjdk.JPG" />Engineering Statics is a free, open-source textbook appropriate for anyone who wishes to learn more about vectors, forces, moments, static equilibrium, and the properties of shapes. Specifically, it has been written to be the textbook for Engineering Mechanics: Statics, the first course in the Engineering Mechanics series offered in most university-level engineering programs. This book鈥檚 content should prepare you for subsequent classes covering Engineering Mechanics: Dynamics and Mechanics of Materials. At its core, Engineering Statics provides the tools to solve static equilibrium problems for rigid bodies. The additional topics of resolving internal loads in rigid bodies and computing area moments of inertia are also included as stepping stones for later courses. We have endeavored to write in an approachable style and provide many questions, examples, and interactives for you to engage with and learn from.</content> </entry> <entry> <id>1077</id> <published>2021-09-28T00:06:14Z</published> <updated>2024-01-22T14:52:27Z</updated> <link rel="alternate" type="text/html" href="https://open.umn.edu/opentextbooks/textbooks/intermediate-fluid-mechanics"/> <title>Intermediate Fluid Mechanics</title> <content type="html"><img alt="Read more about Intermediate Fluid Mechanics" title="Intermediate Fluid Mechanics cover image" class="cover " width="350" height="453" data-controller="common--cover" data-placeholder="/assets/common/placeholder-f8e123f91b7e13ad321132c609842fdd40121f691ee7db391b88763bc42be6a0.webp" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6MjkwNywicHVyIjoiYmxvYl9pZCJ9fQ==--5fe17a37a18bbedc700af587eab235b1cf22bdc0/Title-Page_Intermediate-Fluid-Mechanics-350x453.png" />This book is meant to be a second course in fluid mechanics that stresses applications dealing with external potential flows and intermediate viscous flows. Students are expected to have some background in some of the fundamental concepts of the definition of a fluid, hydrostatics, use of control volume conservation principles, initial exposure to the Navier-Stokes equations, and some elements of flow kinematics, such as streamlines and vorticity. It is not meant to be an in-depth study of potential flow or viscous flow, but is meant to expose students to additional analysis techniques for both of these categories of flows. We will see applications to aerodynamics, with analysis methods able to determine forces on arbitrary bodies. We will also examine some of the exact solutions of the Navier-Stokes equations based on classical fluid mechanics. Finally we will explore the complexities of turbulent flows and how for boundary layer flows one can predict drag forces. This compilation is drafted from notes used in the course Intermediate Fluid Mechanics, offered to seniors and first year graduate students who have a background in mechanical engineering or a closely related area.</content> </entry> <link rel="next">https://open.umn.edu/opentextbooks/subjects/mechanical?page=2</link> </feed>
