Fluid mechanics is a branch of physics that deals with the behavior of fluids, both liquids and gases, and the forces acting upon them. It is a fundamental science that has applications in various engineering fields, including mechanical engineering, civil engineering, aerospace engineering, and chemical engineering. Here are some key concepts and areas within fluid mechanics:

Fluid Properties: Fluids are substances that can flow and conform to the shape of their containers. They are characterized by properties such as density, viscosity (resistance to flow), and compressibility (ability to change volume under pressure).

Fluid Statics: Fluid statics deals with fluids at rest. It describes the behavior of fluids under the influence of forces, such as pressure, and includes concepts like hydrostatic pressure and buoyancy (the force exerted on an object submerged in a fluid).
