Preface Engineering fluid mechanics is an important basic course for related majors. This is a brief bilingual course matching with one-semester 30~40 class hours for both domestic and overseas under-graduates. In this book of six chapters, we stress the governing principles, the assumptions and the method to apply the principles to the solution of practical engineering problems. In chapter 1, some fundamental aspects of fluid mechanics, pressure scales and fluid properties are introduced, including density, viscosity and surface tension. Chapter 2 introduces fluid statics, including forces on fluid, distribution of pressure in fluid at absolute and relative rest, theories and applications of manometer, hydrostatic force on a plane surface and a curved surface etc. Chapter 3 explains methods and concepts for the description of fluid motion, including streamline, system and control volume, and Reynolds transport theorem for the transformation from system to control volume. Emphasis is placed on the fundamental equations of ideal fluid dynamics in chapter 4, including the equation of continuity, the Bernoulli equation and the equation of momentum. The advantages of using dimensional analysis and similarity for planning and simplifying experiments and for organizing test data are featured in Chapter 5. Chapter 6 expands on the internal flow of viscous incompressible fluid, includes energy losses of viscous fluid flow, the flow regimes of laminar and turbulent, practical concerns such as pipe flow, orifice and nozzle flow, and narrow gap flow are also discussed in this chapter. The analysis of some problems and derivation of formulas are appropriately simplified in this book, and there are abundant examples and exercises of fluid transmission, hydraulic pump and valves. Special attention are given to the energy equation of real fluid, calculation of power and efficiency for the systems involving pump and turbine are presented so that the readers can understand and analyze many of the practical problems encountered by the engineer. Through this course, readers should be able to analyze problems independently, make assumptions, establish equilibrium equations, substitute parameters and solve simple engineering problems by using relevant principles. The authors are very much indebted to the textbook funding project of Huaqiao University. This book is edited by Liu Xiaomei, Li Hongyou and Lin Tianliang. Thanks to Yan Jie,
