Centrifugal Pumps
3rd Edition
H.H. Anderson
English
Centrifugal Pumps describes the whole range of the centrifugal pump (mixed flow and axial flow pumps are dealt with more briefly), with emphasis on the development of the boiler feed pump. Organized into 46 chapters, this book discusses the general hydrodynamic principles, performance, dimensions, type number, flow, and efficiency of centrifugal pumps. This text also explains the pumps performance; entry conditions and cavitation; speed and dimensions for a given duty; and losses. Some chapters further describe centrifugal pump mechanical design, installation, monitoring, and maintenance. The various types and applications of pumps in the light of the particular design features involved are addressed in other chapters. This book is authoritative, informative, and thought-provoking to an exceptional extent. It establishes a notable advance in the progress of the art of the designer and manufacturer of centrifugal pumps, to the material advantage of the user.
Engineering Turbulence Modelling and Experiments - 2
Proceedings of the Second International Symposium on Engineering Turbulence Modelling and Measurements, Florence, Italy, 31 May - 2 June, 1993
1st Edition
F. Martelli + 1 more
English
Today understanding turbulence is one of the key issues in tackling flow problems in engineering. Powerful computers and numerical methods are now available for solving flow equations, but the simulation of turbulence effects, which are nearly always important in practice, are still at an early stage of development. Successful simulation of turbulence requires the understanding of the complex physical phenomena involved and suitable models for describing the turbulence momentum, heat and mass transfer. The 89 papers, including 5 invited papers, in this volume present and discuss new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. The high standard of the contributions on the developing and testing of turbulent models attests to the world-wide interest this domain is currently attracting from researchers.
Impinging-Stream Reactors
Fundamentals and Applications
1st Edition
Volume 7
A. Tamir
English
Impinging streams is a unique and multipurpose configuration of a two-phase suspension for intensifying transfer processes in heterogeneous systems, viz. gas-solid, gas-liquid, solid-liquid and liquid-liquid. The essence of the method lies in the collision which results from bringing two streams of a suspension flowing on the same axis in opposite directions. Following the impact of the streams, a relatively narrow zone is created, which offers excellent conditions for enhancing the heat and mass transfer between the phases in the suspension.The following processes are considered in the light of the method of impinging streams: drying of particles, solid-solid and gas-gas mixing, absorption and desorption of gases from liquids, combustion of gas and coal, calcination of phosphate, creation of emulsions, liquid-liquid extraction, dissolution of solids, ion exchange, dust collection and granulation as well as evaporative cooling of air. Additional aspects considered in the book are: power input in performing the above processes, heat and mass transfer coefficient and its correlation, mixing properties of impinging stream reactors, residence time of the particles in the reactors, scale-up of impinging-stream reactors with respect to pressure, drop, hold-up and mean residence time of the particles as well as the heat transfer.The aim of the book is to review the state-of-the-art in the field of impinging streams, to present results of theoretical and experimental research, and to stimulate research and industrial application of the method so that reactors employing impinging streams will become a common tool in chemical engineering and other disciplines of engineering. The major conclusion of this work is that almost any process in chemical engineering can be conducted by impinging streams, resulting in higher efficiency and less power input in comparison with conventional methods.
Work Space, Equipment and Tool Design
1st Edition
Volume 15
A. Mital + 1 more
English
As the ergonomic aspect of many problems facing the industry today attracts more attention from the management, providing scientific knowledge and the know-how to solve such problems is becoming increasingly more important. The impetus for this book originated from the pressing need to make the state-of-the-art ergonomic information on workspace, equipment and tool design available to practising ergonomists, safety specialists, engineering designers, and business and technical managers.The book reinforces the notion that ergonomic data should be explicitly integrated in the design of a system, and should become an indispensable part of the overall design process in production engineering, on an equal basis with such activities as mechanical component design, quality assurance, maintenance, inspection, etc. The focus is on selected ergonomic data for workspace, equipment and tool design, with special emphasis on the practical aspects of applying the available information to specific problem areas.
Fusarium
Mycotoxins, Taxonomy, Pathogenicity
1st Edition
Volume 2
J. Chelkowski
English
Specialists from a number of different disciplines have contributed to this book which presents actual basic and applied findings on Fusarium species, on their metabolites and taxonomy, in connection with pathogenicity to cereal plants and potato tubers. Over 100 metabolites produced by Fusaria are described together with results of studies on their occurrence in agricultural products, their metabolism in farm animals, and possibilities of elmination and detoxification during technological processes. Pathogenic Fusarium species are described from the point of view of their taxonomy, profiles of produced metabolites, ecology, pathogenicity and interaction with cereal tissues. Finally, some actual solutions to avoid cereal grain contamination are discussed, mainly in connection with agricultural practices and breeding programmes.The interdisciplinary and comprehensive nature of the book makes it particularly useful to all who are studying or teaching plant pathology, plant breeding, animal nutrition and any other area in which Fusaria and their metabolites play an important role.

Volume 29
P. Peter
English
Canal and River Levées covers the fundamental principles of canal embankments and levées calculation and design. Canal embankments and levées are amongst the world's oldest hydroengineering structures. This book is divided into seven chapters that focus on solving the problems of protecting control levees, which sometimes called anti-flood or anti-inundation dykes. The opening chapter surveys the general problems of dam design and construction. The next chapters deal with the basic characteristics, determination, experimental methods, and calculations of seepage, as well as the stability calculations and embankment settlement. These topics are followed by discussions of the local conditions and demands relating to the construction of embankments and their various concrete structures. Other chapters explore the requirements of power- and irrigation-canal sealing and the subsoil protection of levees. The last chapter looks into the measurements, general requirements, and observation of dams and levees. This book is intended primarily for civil engineering designers.
