If we are to keep the article objective and easily understandable it is better to separate nucleate boiling transition boiling just like free convection boiling and film boiling are now separate articles It is true that some books merge them together however the calculations for the different regimes are still done separately and not together For example to calculate the heat flux for boiling at film boiling one has to calculate it at nucleate boiling and transition boiling and finally at film boiling By merging them all together you are confusing the reader and assuming them to be the same Most times in engineering it is not really the boiling regime that one is interested in but rather to calculate the total heat flux for say phase change boiling fluids heat exchangers  And I was about to expand the article for transition boiling today only to find it has been removed and redirected  There is still more that can be added to this article on nucleate boiling that i can do
