About this calculator
Overview
Liquid ethylene density varies significantly with temperature and pressure. The calculator uses an empirical correlation valid for the liquid phase below the critical temperature (9.2°C). Ethylene is stored and transported as a cryogenic liquid at -104°C, requiring specialized equipment to maintain its liquid state.

Pro Tips
The calculator uses an empirical formula calibrated for the liquid range: ρ = 214.2 + 465 × (1 - T/Tc)^0.29.
Tc (Critical Temperature) of ethylene is 282.35 K (9.2°C). Above this temperature, the liquid phase cannot exist regardless of pressure.
For industrial piping, always account for the massive thermal expansion of liquid ethylene if it warms up.
The standard unit for density in the chemical industry is kg/m³, which is numerically equal to g/L.
Always check your pressure constraints: this simplified model assumes the substance is at its saturation pressure.

Fun Facts
"Ethylene is the most produced organic compound in the world, primarily used to make plastics like polyethylene."
"In nature, ethylene behaves as a plant hormone that triggers fruit ripening—one 'bad apple' really can spoil the bunch by releasing ethylene gas!"
"Liquid ethylene is extremely cold; it is usually transported at temperatures around -104°C (-155°F)."
"Unlike many other liquids, the density of liquid ethylene changes very rapidly as it approaches its critical temperature (9.2°C)."
"Ethylene was used as an anesthetic in the early 20th century, though its flammability made it dangerous in operating rooms."
"The density of liquid ethylene is roughly half that of water, meaning it would float if they didn't react or mix."
Formula: ρ = 214.2 + 465·(1 - T/Tc)^0.29
