How to Use Liquid Ethylene Density Calculator
The Liquid Ethylene Density Calculator provides two ways to determine liquid ethylene density. Choose direct calculation from measured mass and volume, or estimate density from temperature using built-in reference data.
- Select calculation mode – Choose Direct to calculate density from mass and volume, or Estimate from temperature to look up density at a specific temperature.
- Direct mode – Enter mass in kg and volume in m³. The calculator applies ρ = m/V.
- Temperature mode – Enter the liquid ethylene temperature in °C (range −169 °C to −50 °C). The Liquid Ethylene Density Calculator interpolates from a table of literature reference values.
- Choose density unit – Select kg/m³, g/cm³, or lb/ft³.
- Review the result – The result panel shows the density and the calculation or interpolation steps.
Formula & Theory - Liquid Ethylene Density Calculator
The Liquid Ethylene Density Calculator uses this core formula or rule: the fundamental density relationship:
ρ = m / V| Symbol | Meaning | SI Unit |
|---|---|---|
| ρ | Density | kg/m³ |
| m | Mass | kg |
| V | Volume | m³ |
For temperature-based estimation, the calculator interpolates linearly between reference data points:
| Temperature (°C) | Density (kg/m³) |
|---|---|
| −169 | 583 |
| −160 | 567 |
| −150 | 548 |
| −140 | 527 |
| −130 | 504 |
| −120 | 479 |
| −110 | 451 |
| −104 (boiling point, 1 atm) | 435 |
| −100 | 426 |
| −90 | 396 |
| −80 | 360 |
Assumptions and Limits
- Reference data is for ethylene at approximately atmospheric pressure. Results at elevated pressures will differ.
- Linear interpolation between table points introduces minor error; for precise engineering calculations consult NIST or REFPROP databases.
- Ethylene becomes gaseous above its boiling point at 1 atm (−104 °C). Higher temperatures require pressure to maintain liquid phase.
Use Cases for Liquid Ethylene Density Calculator
The Liquid Ethylene Density Calculator is useful in industrial and academic settings. Common uses include:
- Chemical engineering process design – Estimating liquid ethylene inventory in storage vessels and pipelines.
- Cryogenic storage – Assessing the mass of liquid ethylene held in a cryogenic tank by volume measurement.
- Physical property lookup – Quickly retrieving reference density values for laboratory or design calculations.
- Education – Illustrating how density varies with temperature for cryogenic liquids in physical chemistry or chemical engineering courses.
The Liquid Ethylene Density Calculator provides a transparent, browser-based tool for quick reference without requiring dedicated thermodynamic software.
