Properties of Superheated Steam

Table C.4 Properties of Superheated Steam (English Units)...

To make use of the steam tables, you must first locate the region of the phase diagram in which the state lies. The tables are organized so that the saturation properties are given separately from the properties of superheated steam and subcooled liquid. Examine the large set of tables in the back of the book. In addition, the saturation properties are presented in two ways (1) the saturation pressure is given at even intervals for easy interpolation, and (2) the saturation temperature given at even intervals for the same reason. 

Another property of superheated steam which in chemical operations should prove valuable, but which up to the present has not been utilised to the extent which it deserves, is that of yielding in proportion to its effectiveness less water on condensation than saturated steam. If, as is often the case in chemical operations, we use live steam for heating up a liquid either to its boiling point or to a point below it, the bulk of the liquid at the end of the operation will increase by the amount of steam which becomes condensed naturally this amount will be less when we use superheated than when saturated steam is employed.
