Ethylene - Thermal Conductivity vs. Temperature and Pressure
Calculate and view thermal conductivity of ethylene as a function of temperature and pressure. Thermal conductivity is a material property that describes the ability to conduct heat. This tool provides data in both SI units (mW/m K) and Imperial units (Btu(IT)/(h ft °F), kcal(IT)/(h m K), and (Btu(IT) in)/(h ft2°F)).
| State | Temperature (K) | Temperature (°C) | Temperature (°F) | Pressure (bara) | Pressure (psia) | Thermal Conductivity (mW/m K) | Thermal Conductivity (kcal(IT)/(h m K)) | Thermal Conductivity (Btu(IT)/(h ft °F)) | Thermal Conductivity ((Btu(IT) in)/(h ft2°F)) |
