Fluid Mechanics studies the behavior of fluids (liquids and gases) at rest (fluid statics) and in motion (fluid dynamics). The chapter begins with fundamental properties like density (ρ), pressure (P), and viscosity (η), then explores: Pascal’s Law: Pressure transmission in confined fluids, Archimedes’ Principle: Buoyant force, Bernoulli’s Equation: Energy conservation in flowing fluids, Viscous drag (Stokes’ Law) and turbulence (Reynolds number), Applications range from hydraulic systems to aerodynamics, with problem-solving focused on manometers, flow rates, and lift forces.
This chapter covers use of Archimedes Principle of flotation. Justify how ships are engineered to float in the sea. Define and apply the terms steady. Explain and apply Bernoulli's equation for horizontal and vertical fluid flow. Explain why real fluids are viscous fluids. Describe how viscous forces in a fluid cause a retarding force on an object moving through it.
