Introduction: thermodynamic and molecular-kinetic methods for studying thermal properties of matter; definitions and units of thermodynamics (substances, systems–fixed mass and fixed space, pressure, state of a system, process).
•Temperature: the zero law of thermodynamics; the constant-volume gas thermometer, the temperature scales, and thermometers.
•Thermal expansion of solids and liquids
•Heat: the mechanical equivalent of heat; specific heat; calorimetry; heat transfer modes.
•Macroscopic and microscopic descriptions of an ideal gas: mass and size of molecules; bases of molecular-kinetic theory; equation of state of an ideal gas; constant-volume, constant-temperature and constant-pressure processes, a molecular model for the pressure of an ideal gas; mean energy of molecules; the number of degrees of freedom; molecular interpretation of temperature; the mean velocity of the molecules; the root-mean-square (rms) speed; the most probable velocity; the Maxwell distribution.
This course provides a fundamental understanding of fluid mechanics. Starting from the definition of a fluid, theory will be build up in order to describe, characterize, analyze and understand the behavior of fluids (gases, liquids) in motion or static. Mechanics of fluids is a fundamental subject and one that finds many applications in meteorology and in aeronautics. In engineering several industrial and technological applications are found from ship design to pipe modeling.
The following topics will be covered:
Introduction: Basic concepts of fluid mechanics Fundamental term; Physical value; Fluids and their properties; Forces inside fluid.
Fluid Statistics: Pascal’s law; Euler’s equation of fluid statics; Measurement of pressure; Relative statics of fluid-constant acceleration, rotation; Forces of hydrostatic pressure; Buoyancy; Flotation; Stability. Surface tension' Capillary Action and Cavitation.
Fluid Kinematics: Euler and Lagrangian specification of fluid flow; Streamlines; Pathlines; Stream surface; Stream tube; Mass/volume flow; Control volume.
