This course spans approximately 120 hours over two semesters and provides 12 credits. AIMS AND CONTENT LEARNING OUTCOMES The main objective of this course is to introduce 2nd year students to the concepts of Fluid Mechanics, such as fluid and flow properties,fluid behavior at rest and in motion. Fundamental equations, like mass and momentum balances for simple one-dimensional steady flows, will be formally derived and applied to the study of pipe and open-channel flow. AIMS AND LEARNING OUTCOMES Evaluation of static forces on immersed plane and curved surfaces. Design and analysis of simple pipe networks, fluid machineries. Steady flow profiles in open channels. TEACHING METHODS The lectures are organized in about 70 hours of theory and in about 50 hours of practice, with example problems. LECTURES WILL BE DELIVERED IN CLASS SYLLABUS/CONTENT Fundamentals - Fluid properties and classification. Dimensional analysis and the Buckingham Pi Theorem. Cauchy's continuum, forces, pressure and stresses. Stress in a fluid at rest. Hydrostatic law. Stress in a fluid in motion. Material and local derivatives. Conservation of mass and momentum principle in integral and local form. Inviscid fluid and the Bernoulli's law. Fluid at rest: hydrostatics - Pressure distribution in an uncompressible fluid and in a compressible, barotropic fluid. Forces on immersed plane and curved surfaces. Buoyancy. Stability of floating and immersed bodies. Fluid in motion: one-dimensional flow - Definition of cross-averaged quantities. Conservation of mass and momentum principle for a one dimensional flow: continuity and momentum equations. Flow in pipes - Uniform and steady flow in a pipe. Friction losses. Local dissipations of energy. Design and analysis of simple pipe networks, fluid machineries. Flow in open channels - Uniform and steady flow in a channel. Friction losses. Uniform flow depth. The critical state. Critical flow depth. Subcritical and supercritical flow. Gradually varied flow. Flow profiles. Rapidly varied flow: the hydraulic jump, flow in constrictions. Outline of unsteady flow in channels: the kinematic wave.
