From Airplanes to Weather Patterns

Fluid dynamics studies how liquids and gases move and interact with their surroundings. It explains everything from blood flow in the body to how planes fly.

Key Concepts

• Pressure: The force exerted per unit area.
• Buoyancy: Why objects float or sink in a fluid.
• Bernoulli’s Principle: Fast-moving fluid has lower pressure than slow-moving fluid.

Real-World Connections

Understanding fluids is key for engineering, meteorology, medicine, and environmental science.

Useful Equation

Bernoulli’s equation helps explain fluid motion:

\[ P + \frac{1}{2}\rho v^2 + \rho gh = \text{constant} \]

Where \( P \) is pressure, \( \rho \) is density, \( v \) is velocity, \( g \) is gravity, and \( h \) is height.
