Introductory course on fluid mechanics.
The aim of the course is to provide the student with basic knowledge on the motion of fluids. At the end of the course the student will have acquired knowledge that will make him able to:
The teaching is divided into lectures held by the teacher, in which the theory will be exposed and exercises.
In the lectures, the theory will be applied to different examples.
In the part devoted to exercises, the student will carry out independently exercises proposed by the teacher. The exercises will be corrected in the classroom by the teacher.
The Continuum assumption. Physical properties. Forces acting on a fluid. Pressure and stress in fluids. State equation.
Stress in a fluid at rest. Integral and differential equations for a fluid at rest. Pressure distribution in a constant density fluid and in an ideal gas subject to gravity. Pressure forces on plane surfaces. Pressure forces on curved surfaces. Pressure variation across interfaces. Surface tension.
Eulerian and Lagrangian description of the flow. Material derivative. Velocity and acceleration. Transport Theorem.
Stress in a moving fluid. Mass conservation principle and its integral formulation. Momentum principle and its integral formulation. Integral formulation of the angular momentum law. Applications of the integral formulation of fluid flow (Force of a jet on a surface, Borda losses). Ideal fluids and Bernoulli theorem with applications ( efflux through a hole in the side of a tank, stagnation pressure, Pitot tube)
Characteristic quantities (averaged velocity, discharge, The Piezometric Head, Kinetic Head, Total Head). Continuity equation. Momentum equation. Steady uncompressible flow in circular ducts. Bernoulli Theorem. Flow measurements devices (Venturi meter, thin plate orifice, flow nozzle). Fundamentals on hydraulics networks.
Dimensional analysis and Pi theorem. Applications (drag and lift on a body moving in a fluid).Model testing and similitude

The exam consists of a first written part (1 exercise) and an oral part.
The written test will be corrected immediately after the conclusion of the same.
In order to access the oral part it is necessary to have passed the written test.
The oral part will take place immediately after the correction and passing the written test.
It is not possible to repeat the exam in the session following the one in which the student did not pass.
In order to take the exam of the course the student must have passed the exams of "GENERAL PHYSICS" and "CALCULUS I
The written part of the exam is aimed at ascertaining that the student has acquired the necessary tools to solve simple problems of Hydrodynamics. The oral part is aimed at verifying the student's understanding of the course topics.
