A good knowledge of Fluid mechanics is essential for Chemical, Mechanical and Civil engineers. As a result it is taught at a very early stage in degree courses on those disciplines. A First Course in Fluid Mechanics covers the basics of the engineering fluid mechanics without delving into deeper more mathematical concepts. Building from most basic concepts such as physical properties of fluids, it covers the topics in fluid statics and dynamics. Hydrostatic pressure, buoyancy and forces on immersed bodies are discussed under fluid statics. Under fluid dynamics, Bernoulli’s principle is introduced. Furthermore, the nature of fluid flows is discussed in engineering context. Laminar and turbulent flows in pipes are explained in detail. Finally hydraulic design is discussed paying attention to pump capacity calculations. This textbook is levelled at first year undergraduate students.
