Introduction
In this unit, we explore how fluids behave both at rest and in motion: how pressure works, how flow is maintained, and how energy is conserved in moving fluids. Topics include hydrostatics, fluid flow, Bernoulli’s equation, continuity, viscosity and more.
Summary of Key Equations
1. P = ρ·g·h (Pressure in a fluid at depth)
2. A₁·v₁ = A₂·v₂ (Continuity equation for incompressible flow)
3. P + ½·ρ·v² + ρ·g·h = constant (Bernoulli’s equation – energy in flowing fluid)
4. F₍drag₎ = ½·C₍d₎·ρ·A·v² (Drag force approximation – optional/advanced)
