Explore atmospheric and fluid pressure

Pressure in a fluid increases with depth: P = P₀ + ρgh. Pascal's Principle states that pressure applied to a confined fluid transmits undiminished in all directions — the basis for hydraulic systems. Atmospheric pressure at sea level is ~101.3 kPa, decreasing with altitude. Bernoulli's Equation shows the trade-off between pressure, kinetic energy, and height in flowing fluids.
