The equation developed by Rohsenow (1952) for correlating heat transfer data for surface-boiling liquids is evaluated. It is suggested that the nucleate boiling equation may be based on inadquate analyses of published heat transfer data, and may be an unreliable means of predicting boiling heat transfer rates for systems that have not been tested in advance. The difficulties involved in obtaining a generalized correlation equation which accounts for the geometry, surface tension and superheat in pool boiling is assessed. It is hypothesized that, while Rohsenow's equation may have considered the buoyancy effect due to the ratio of the densities of the vapor and liquid phases, the inertial effect of the ratio also needs to be incorporated into the analysis.

How is boiling point used in chemistry?
If you know a boiling point, you can separate two different liquids that are mixed together. If the two liquids have different boiling points, you can boil them both. One of the liquids will reach its boiling point before the other liquid and start to evaporate. One of the liquids will have evaporated and will be separated from the liquid with the higher boiling point. This is called distillation. Jarachia ~ x

Boiling points vary from liquid to liquid.

Why is it possible to separate mixtures of liquids by boiling?
It is possible to separate mixtures of liquids by boiling because each component of the mixture has a different boiling point. When the mixture is heated, the component with the lowest boiling point will vaporize first, leaving behind the other component. The vapor can then be condensed back into a liquid, resulting in the separation of the two components.
Which two or more liquids can be separated based on their boiling points?
Two or more liquids can be separated based on their boiling points through a process called distillation. Distillation is particularly effective when the liquids have significantly different boiling points. For example, a mixture of water and ethanol can be separated by distillation because ethanol has a lower boiling point than water.
