⚗️ Density Fundamentals

Definition: Mass per unit volume (ρ = m/V)

Temperature Effect: Most materials expand when heated (density decreases)

Pressure Effect: Liquids/solids slightly compressible, gases very compressible

Buoyancy: Objects float if their density < fluid density

Specific Gravity: Density relative to water at 4°C

🏗️ Engineering Applications

Structural Design: Material selection, load calculations

Fluid Mechanics: Pressure calculations, pump sizing

Materials Science: Porosity analysis, quality control

Environmental: Pollution concentration, soil analysis

Manufacturing: Mixing ratios, product specifications

🌊 Fluid Density Applications

Hydrostatic Pressure: P = ρgh (depth pressure)

Archimedes Principle: Buoyant force = ρ_fluid × V_displaced × g

Flow Calculations: Reynolds number Re = ρvL/μ

Mixing: Density differences drive natural convection

🔬 Density Measurement Methods

Pycnometer: Precise volume measurement for liquids

Hydrometer: Float-based measurement for liquids

Density Meter: Electronic oscillating tube method

Gas Displacement: For porous solids (powder, foam)

Archimedes Method: Weighing in air vs fluid

🌌 Extreme Densities

Lightest: Aerogel ~1 kg/m³ (lighter than air)

Gases: Hydrogen ~0.09 kg/m³, Helium ~0.18 kg/m³

Heavy Elements: Osmium ~22,600 kg/m³ (densest natural)

White Dwarf: ~10⁹ kg/m³ (1 ton per cm³)

Neutron Star: ~10¹⁷ kg/m³ (nuclear density)

Black Hole: Varies enormously with size

🧪 Laboratory & Industrial Standards

Water (4°C): Exactly 1000 kg/m³ (reference standard)

STP Conditions: 0°C, 1 atm for gas densities

API Gravity: Petroleum industry standard (°API)

Baumé Scale: Historic hydrometer scale

Quality Control: Density as purity indicator
