This textbook on fluid mechanics is aimed at engineering students at Bachelor's degree level. In Chapter 2 the fundamentals of fluid mechanics, needed for the description and analysis of flows in technology, are presented. One-dimensional stream filament theory, along with the momentum integral and angular momentum integral equations, already present us with one method of constructing fluid technological appliances and experiments. For example, the dimensions of a machine can be determined quite accurately in one first step and predictions made about the flow losses which occur.
However, these methods fail when machines are to be optimized, or when appliances are to be developed to operate under extreme conditions, such as silent operation, high efficiency, small dimensions, greatly damped oscillatory behavior, etc. In addition to this, even for most simple cases of application, simple fluid mechanical fundamentals cannot determine the operating behavior of a machine accurately enough. This requires extensive experiments to be carried out and these can be very costly and time consuming.
At this point we refer to more detailed textbooks which progress systematically from the fundamental fluid mechanical equations and their methods of solution to the application of fluid mechanical software.
The methods used in fluid mechanics are analytical, numerical and experimental. Although numerical methods are increasingly used to replace experimental methods, all three are still needed to solve fluid mechanical problems. This book is restricted to theoretical, that is analytical, methods. After working through this book, students are qualified to understand the basics and phenomena of fluid mechanics, and will have obtained an initial insight into fluid mechanical software, even if further studies into the fundamental equations of fluid mechanics and numerical methods are necessary for the application of this software.
The composition of this book is partly very theoretical. In order not to lose sight of the connection to technical applications during the extensive derivations, we have selected flows past airplane wings, flows past vehicles and flows in pipes of process engineering systems as representative examples to illustrate the basics of one-dimensional fluid mechanics.
We now introduce the student to the great variety of fluid mechanical applications, demonstrating that flows are all around us in our technological environment, by describing selected examples of flows in the following introductory sections.

STAAD Foundation is a comprehensive foundation design program that offers the ability to model complex or simple footings, including those specific to Plant facilities such as octagonal footings supporting vertical vessels, strap beam foundations supporting horizontal vessels, ring foundations supporting tank structures, and drilled or driven pier foundations.
Common foundations such as isolated footings, combined footings, strip footings, pile caps, and mat foundations can also be designed for larger structures or using parametric wizards. It provides a streamlined workflow through its integration with STAAD.Pro and can also be used as a stand-alone program.
Efficient design and documentation is realized through its plant-specific design tools, multiple design codes with U.S. and metric bar sizes, design optimization, and automatic drawing generation. The plant-specific tools include vertical vessel foundations (octagonal and square shape supported on soil or on piles), and heat exchanger foundations (combined, two isolated and two isolated with a grade beam), tank ringwall foundations, and driven or drilled pier foundations.
Powerful modeling includes a physical modeling system, a toolkit mode, automatic pile arrangement, and FEM, which allows complex or simple layouts. The foundation toolkit mode was introduced to address the needs of special footing types like drilled pier and dead man anchor guy foundations.
Productivity is increased through the ability to utilize the structural model with the foundation model through the integration with STAAD.Pro. Changes made in the STAAD.Pro model are tracked and can be merged automatically with the foundation model. View the integrated video.

Hi Colleagues,
I urgently need the proceedings of the 5th International Conference on Case histories in geotechnical Engineering (2CD roms and a printed abstracts volume), held in New-York 2004 and organised by the University of Missouri-Rolla. The conference Chairman is Shamsher Prakash.
Dear all,
please can you provide me with this books
1) Maximizing AutoLISP by Joseph Smith and Rusty Gesner
2) AutoLisp: Programming for Productivity by William Kramer
3) AutoLisp Treasure Chest by William Kramer
Galvanizing is an established means of protecting steel reinforcement and other embedded components against corrosion in concrete. This book presented critical assessment of the characteristics and use of galvanized steel in concrete. Apart from a number of small surveys and reviews interspersed through the technical literature over the last few years, the most comprehensive single document covering this topic was Galvanized Reinforcement for Concrete - II, published by the International Lead Zinc Research Organization in 1981. A thorough updating of this reference source was long overdue and the publication of this book is intended to bridge that gap. This reference provides a detailed resource covering all aspects of this important material. Both servicability and durability aspects are well covered, with all the information needed maximise the life of buildings constructed from it.

Fatigue is a major issue affecting safety and quality of service in the railway industry. This book reviews key aspects of this important subject. It begins by providing an overview of the subject, discussing fatigue at the wheel-rail interface and in other aspects of infrastructure. It then considers fatigue in railway and tramway track, looking at causes of potential failure in such areas as rails and fixings as well as sleepers. It also reviews failure points in structures such as embankments and cuttings. The book then analyzes fatigue in railway bridges, looking in particular at masonry arch bridges as well as metal and concrete bridges. Two final chapters review safety and reliability issues affecting escalators and lifts.
