Heat transfer properties

The following formulas can be used to calculate the specific heat, thermal conductivity, density and vapor

pressure of 3M™ Fluorinert™ Electronic Liquid FC-40 at various temperatures.

Specific Heat (J kg-1 °C-1) = 1014 + 1.554 (T, °C)

Thermal Conductivity (W m-1 °C-1) = 0.067 – 0.000069 (T, °C)

Density (kg/m3) = 1909 – 2.16 (T, °C)

Log10 (Vapor Pressure (pa)) = 10.448 – (2381/(T, K))

The following graph can be used to determine the viscosity of Fluorinert liquid FC-40 over the indicated

temperature range.
