Introduction to Fluid Mechanics

This lecture introduces the fundamental concepts of fluid mechanics, covering topics such as fluid properties, pressure, viscosity, and the behavior of fluids at rest and in motion. It explores the characteristics of solids, liquids, and gases, as well as the analysis of fluid behavior through Newton's laws and conservation principles. The lecture delves into the definition of pressure, the ideal gas law, and the concept of fluidity. It also discusses the speed of sound in fluids, vapor pressure, and surface tension. Additionally, it examines the equilibrium of fluids in containers of various shapes and the hydrostatic pressure variation in incompressible fluids.
