14. In a separate measurement over a wide range of Pr, we find (Formula presented) (unpublished). As the change in Pr for our data is mostly due to the kinematic viscosity (Formula presented) (it more than doubled), we treat the thermal diffusivity (Formula presented) (change (Formula presented) as a constant. This gives (Formula presented). Ignoring a possibly weak Pr dependence of Nu, we have (Formula presented) which leads to (Formula presented)
