1. What is Density of Liquid CO₂?

Definition: Density is the mass per unit volume of a substance. For liquid CO₂, it's typically measured in kg/m³.

Typical Value: Liquid CO₂ has a density of ~1100 kg/m³ at high pressure (e.g., 5.1 MPa).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of CO₂ is divided by its volume to calculate density.

3. Importance of Liquid CO₂ Density

Details: Knowing density is crucial for storage, transportation, and industrial applications of liquid CO₂.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why does CO₂ density vary?
A: Density changes with temperature and pressure. Higher pressure increases density.

Q2: What's the typical density range for liquid CO₂?
A: At standard storage conditions (20°C, 5.7 MPa), it's about 770 kg/m³. At higher pressures (~5.1 MPa), it's ~1100 kg/m³.

Q3: How does temperature affect density?
A: Density decreases as temperature increases at constant pressure.

Q4: What units are used for CO₂ density?
A: kg/m³ is standard, but g/cm³ or lb/ft³ are sometimes used.

Q5: Why is liquid CO₂ density important?
A: It's critical for designing storage tanks, pipelines, and calculating quantities for industrial processes.
