Before revision: The data can be correlated by equation of the form , The Nusselt numberis defined as, where q/A is the total heat flux, is the maximum bubble diameter as it leaves the surface, is the excess temperature, is the thermal conductivity of the liquid and is the Prandtl number of the liquid .
