The complete reference for engineers and designers working on pump design and development, or using centrifugal pumps in the field. This authoritative guide has been developed with access to the technical expertise of the leading centrifugal pump developer, Sulzer. In addition to providing the most comprehensive centrifugal pump theory and design reference, with detailed material on cavitation, erosion, selection of materials, rotor vibration behaviour and forces acting on pumps, the Handbook also covers key pumping applications topics and operational issues including operating performance in various types of circuitry, drives and acceptance testing.
* Enables readers to understand, specify and utilise centrifugal pumps more effectively
* A complete centrifugal pump engineering guide. The Handbook covers theory, design and operation, with an emphasis on providing a high levels of rigorous data, design detail, and industry-leading quality and efficiency solutions for high capital outlay pump plant users.
* Draws on the world-beating experience of Sulzer, the leading centrifugal pump developer, making this a particularly valuable resource
* Third edition, updated to cover the latest design and technology developments, applications, test and reliability procedures, cavitation, erosion, selection of materials, rotor vibration behaviour, operating performance in various types of circuitry, new drive technology and acceptance testing.

Wim Wenders: Making Films That Matter is the first book in 15 years to take a comprehensive look at Wim Wenders's extensive filmography. In addition to offering new insights into his cult masterpieces, the 10 essays in this volume highlight the thematic and aesthetic continuities between his early films and his latest productions. Wenders's films have much to contribute to current conversations on intermediality, whether it be through his adaptations of important literary works or his filmic reinventions of famous paintings by Edward Hopper or Andrew Wyeth. Wenders has also positioned himself as a decidedly transnational and translingual filmmaker taking on the challenge of representing peripheral spaces without falling into the trap of a neo-colonial gaze. Making Films That Matter argues that Wenders remains a true innovator in both his experiments in 3D filmmaking and his attempts to define a visual poetics of peace.

Swiss critic Johann Georg Sulzer's Dialogues on the Beauty of Nature (1750) and Reflections on Certain Topics of Natural History (1745) are exemplary specimens of eighteenth-century European theology, philosophy, natural history, and aesthetics. Sulzer's contemporaries-notably Goethe-read him with attention. Eric Miller's elegant translation comes with a vivid, informative, and strongly contextualizing introduction. Sulzer's early works are a curio cabinet of the philosophical and theological arguments that exercised and enticed the intelligentsia of his period. These topics and arguments have by no means forfeited pertinence today.

Why does a clarinet play at lower pitches than a flute? What does it mean for sounds to be in or out of tune? How are emotions carried by music? Do other animals perceive sound like we do? How might a musician use math to come up with new ideas? This book offers a lively exploration of the mathematics, physics, and neuroscience that underlie music in a way that readers without scientific background can follow. David Sulzer, also known in the musical world as Dave Soldier, explains why the perception of music encompasses the physics of sound, the functions of the ear and deep-brain auditory pathways, and the physiology of emotion. He delves into topics such as the math by which musical scales, rhythms, tuning, and harmonies are derived, from the days of Pythagoras to technological manipulation of sound waves. Sulzer ranges from styles from around the world to canonical composers to hip-hop, the history of experimental music, and animal sound by songbirds, cetaceans, bats, and insects. He makes accessible a vast range of material, helping readers discover the universal principles behind the music they find meaningful. Written for musicians and music lovers with any level of science and math proficiency, including none, Music, Math, and Mind demystifies how music works while testifying to its beauty and wonder.

The writings of Sulzer and Koch represent a significant confluence of philosophical and musical thought from the German Enlightenment. Koch creatively adapted many of Sulzer's abstract philosophical ideas to concrete questions of musical pedagogy, showing how they could be usefully applied to the teaching and analysis of musical composition. This collaborative study and translation of the texts will be of interest to all historians of music, music theory, and historians of eighteenth-century German aesthetic thought.
