En este libro se abordan los temas de diseño de los intercambiadores de calor tubulares desde la perspectiva del diseño mecánico. En el mismo se profundiza en la nomenclatura e identificación de intercambiadores de calor y los elementos constitutivos, asi como los factores que intervienen para una adecuada selección de materiales. Además se abordan los procesos de manufactura involucrados en la fabricación y las recomendaciones para instalación, operación y mantenimiento de cambiadores de calores.

Los sistemas computarizados de control del motor se desarrollaron originalmente para ayudar a los vehículos a satisfacer las regulaciones de emisiones especificadas por el gobierno. Un sistema típico consta de una computadora, sensores de información y actuadores de salida que actúan recíprocamente el uno con el otro para reunir, almacenar y enviar datos para controlar virtualmente todas las operaciones del motor.

salud y seguridad

Se realiza un estudio teórico acerca de los aspectos que afectan la salud y seguridad en los operarios de soldadura y corte. Se dan a conocer los riesgos a la salud que provoca la realización del proceso de soldadura, se enfatiza en los daños provocados por el humo producto de este proceso y se señalan algunas de las medidas que pueden tomarse para eliminar o disminuir estos efectos nocivos.

In the year 2000, the Max-Planck-Institut für Metallforschung in Stuttgart, in conjunction with other materials-related institutes of the Max Planck Society, and institutes and universities from all over Europe, decided to prepare a White Book on the topic of “Strategies for Future Areas of Materials Science and Basic Research in Europe.” Preparation of this White Book has involved extensive consultation with leading materials scientists, primarily within Europe (most notably from the CNRS in France and the MPG in Germany), but also from the United States and Japan. Discussions were also undertaken with industrial research directors and relevant policy makers.

AutoCAD 2002 is the most powerful CAD software product available for PCs today. It can perform nearly any drawing task you can give it. This book is designed to be your comprehensive guide to the entire AutoCAD program. AutoCAD 2002 is the fastest, smoothest AutoCAD yet. Certain features have been added that are not even mentioned in this book because you never see them — you just notice that fewer regenerations occur, drawings load faster, and you spend less time waiting while drawing and editing. In addition to these refinements, of course, are the many new features covered in this book that will make your drawing easier and faster. The new features include both those introduced with 2000, an interim release, and 2002. This book covers every major AutoCAD feature. If you’re a beginning AutoCAD user, you’ll find everything you need to start out; if you’re already using AutoCAD regularly, the book covers advanced material as well. It provides a solid reference base to come back to again and again, as well as short tutorials to get you drawing. Sidebar profiles show how companies out in the real world use AutoCAD. Finally, the CD-ROM is chock full of drawings, a trial version of AutoCAD 2002, and AutoLISP programs. This book should be all you need to make full use of that expensive program called AutoCAD.

Preface The purpose of writing this book is to produce a text suitable for those in Further and/or Higher Education who are required to learn how to use the CAD software package AutoCAD®2008. Students taking examinations based on computer-aided design will find the contents of the book of great assistance. The book is also suitable for those in industry who wish to learn how to construct technical drawings with the aid of AutoCAD 2008 and those who, having used previous releases of AutoCAD, wish to update their skills in the use of AutoCAD. The chapters dealing with two-dimensional (2D) drawing will also be suitable for those who wish to learn how to use AutoCAD LT 2008, the 2D version of this latest release of AutoCAD. Many readers using AutoCAD 2002, 2004, 2005, 2006 or 2007 will find the book’s contents largely suitable for use with those versions of AutoCAD, although AutoCAD 2008 has enhancements over AutoCAD 2002, 2004, 2005, 2006 and 2007 (see Chapter 21). The contents of the book are basically a graded course of work, con- sisting of chapters giving explanations and examples of methods of con- structions, followed by exercises which allow the reader to practise what has been learned in each chapter. The first 12 chapters are concerned with constructing technical drawings in 2D. These are followed by chapters detailing the construction of three-dimensional (3D) solid drawings and rendering. The two final chapters describe the Internet tools of AutoCAD 2008 and the place of AutoCAD in the design process. The book finishes with three appendices: printing and plotting; a list of tools with their abbreviations; a list of some of the set variables upon which AutoCAD 2008 is based. AutoCAD 2008 is very complex computer-aided design (CAD) soft- ware package. A book of this size cannot possibly cover the complexities of all the methods for constructing 2D and 3D drawings available when working with AutoCAD 2008. However, it is hoped that by the time the reader has worked through the contents of the book, they will be suffi- ciently skilled with the methods of producing drawing with the software, will be able to go on to more advanced constructions with its use, and will have gained an interest in the more advanced possibilities available when using AutoCAD.

The enterprise that plastics and the plastics industry have formed is nothing short of phenomenal. An entirely new industry emerged creating employment for an estimated 5 million people worldwide. The plastic products produced and used worldwide have made a major contribution to the progress of materials and civilization. The industry is too young to begin to surniise its final direction.

termodinamica

toda ciencia posee un vocabulario único y la termodinámica no es la ex- cepción. La definición precisa de conceptos básicos constituye una base sólida para el desarrollo de una ciencia y evita posibles malas interpreta- ciones. se trata de la novena edicion en idioma español del excelente libro de CEngel

mecanica de fluidos

la mecánica de fluidos es un tema atractivo y fascinante, con aplicaciones prácticas ilimitadas, que van desde los sistemas biológicos microscópicos hasta los automóviles, los aviones y la propulsión de naves espaciales. la mecánica de fluidos también ha sido históricamente una de las asignaturas más desafiantes para los estudiantes de ingenieria, porque el análisis adecuado de los problemas de mecánica de fluidos no sólo requiere el conocimiento de los conceptos, sino también experiencia e intuición física
