Fig. B.1 Various properties of liquid water including: viscosity (μ, ●), density (ρ, ∘), heat capacity (Cp, ), thermal conductivity (k, ), a group of parameters used in the calculation of the Rayleigh number (, see the text for the definition of the parameters used to determine , ) and the Prandtl number (Pr, ). The dimensions for each parameter are given in the equation and their magnitude on the graph can be ascertained by putting 0 °C in the equation. All the equations in the graph have the temperature T in °C.
