What you will learn in Fluid Mechanics

1. Pressure and Depth
Pressure in a static fluid grows linearly with depth, and the slope depends entirely on density.
2. Pascal's Principle
Pressure applied to an enclosed fluid is transmitted equally everywhere — the entire basis of hydraulic machinery.
3. Buoyancy & Archimedes' Principle
Floating, sinking, and neutral buoyancy all come down to one density comparison.
4. Fluid Statics vs. Fluid Dynamics
Still fluids and flowing fluids obey different rules of thumb — knowing which applies is half the problem.
5. Continuity Equation
Fluid can't pile up or vanish inside a pipe — narrowing it forces speed up to keep the flow rate constant.
6. Bernoulli's Principle
Faster-moving fluid trades away pressure — the same speed increase continuity requires shows up as a pressure drop.
7. Viscosity & Real Fluid Flow
Real fluids resist flowing past themselves — viscosity is exactly that internal friction.
8. Flight and Lift
A wing's lift is Bernoulli's principle applied to airflow moving faster over the top surface than the bottom.
9. Hydraulic Machinery
Car jacks and brake systems are Pascal's principle wearing a real-world name.
10. Surface Tension and Capillarity
A liquid's surface pulls like a stretched skin — raising the pressure inside drops and bubbles, and lifting or sinking a liquid in a narrow tube according to its angle of contact.
