I'm curious as to why steam tables typically present liquid properties with an "f" subscript, such as ρf.The gas properties use a "g" subscript, so I would expect the liquid properties to use "l". My first guess at the meaning of the "f" would be that it means "fluid", but this wouldn't make sense since both liquids and gases are subcategories of fluids. Am I missing something obvious?

ASME steam tables are also presented this way but I can't find any free examples online.
