T = temperature, ρ = density, μ = dynamic viscosity, cp = specific heat, k = thermal conductivity,. Pr = Prandtl number, β = volume expansion coefficient. According to the literature “New International Formulation for the Thermal Conductivity of H2O”, the thermal conductivity of water at 20 °C is W/m·K. An equation for the thermal conductivity of water and steam is formulated in the temperature range from 0 to °C and in the pressure range from the triple.

Water possesses highest density at 0C temperature and thus highest thermal conductivity. Generally, for pure water pH is 7 at a particular temperature and. Thermal Conductivity ; Ice. ; Glass,ordinary. ; Concrete. ; Water at 20° C · ; Asbestos. Therefore, you will get a more severe burn from boiling water than from hot tap water. Conversely, if the temperatures are the same, the net heat transfer.
