Online calculator, figures and tables showing thermal conductivity of liquid and gaseous propane at varying temperarure and pressure, SI and Imperial units
Thermal conductivity is a material property that describes ability to conduct heat. Thermal conductivity can be defined as
"the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions"
The SI unit used for thermal conductivity is [W/m K], while a common Imperial unit is [Btu/h ft °F].
The thermal conductivity of propane depends on temperature and pressure as shown in the figures and tables below.
Online Propane Thermal Conductivity Calculator
The calculator below can be used to estimate the thermal conductivity of propane at given temperature and atmospheric pressure.
Note! Propane boiling point at atmospheric pressure is -42 °C (-44°F), and hence, there is a shift in conductivity at that temperature.
The output thermal conductivity is given as mW/(m K), Btu(IT)/(h ft °F), (Btu(IT) in)/(h ft2 °F) and kcal(IT)/(h m K).
