Fluid Mechanics investigates the behavior of fluids (liquids and gases) at rest and in motion, introducing fundamental principles essential for engineering, meteorology, and biomechanics. The chapter begins by defining key properties like density (ρ), pressure (P), and viscosity (η), establishing Pascal's Law for pressure transmission
in confined fluids and Archimedes' Principle of buoyancy. Advanced topics include Torricelli's theorem for efflux velocity and Poiseuille's Law for laminar flow. Fluid Mechanics studies the behavior of liquids and gases at rest (fluid statics) and in motion (fluid dynamics). This chapter forms the foundation for understanding phenomena like buoyancy, fluid flow, and pressure systems, with applications in engineering, meteorology, and biomechanics.Ch-06: Fluid Mechanics - Short Question Answers
