To use a saturated steam table, you must know either the temperature or the pressure of the steam with which you're dealing--but not both. According to the scientific resource eFunda, these values are "mutually dependent"--as one changes, so will the other, in a predictable, standard manner. As is the case with other values, saturated steam tables provide temperature and pressure in both metric and imperial units--degrees Celsius and Fahrenheit--for temperature and "bars" and "psi" for pressure, respectively.
Saturated steam tables also provide values for the density and volume of steam when the pressure or temperature is known. As is the case with pressure and temperature, the table provides these figures in both metric and imperial units, which are kilograms per meter cubed or pounds per foot cubed for pressure and meters cubed per kilogram or feet cubed per pound for volume, respectively. Unlike the more basic properties, however, the table offers density and volume for steam on both sides of the boiling point, whether it's a "saturated liquid" on the verge of becoming steam or a "saturated vapor" that is just crossing the threshold.
While "entropy" measures the relative disorder of a gas, its "enthalpy" represents the sum of the internal energy present within a gas chamber, thst is, gas pressure times its volume. Saturated steam tables include both of these values for steam, again in both metric and imperial units. The tables provide enthalpy values in kilojoules per kilogram (metric) and British thermal units per pound (imperial), while entropy is available in either kilojoules per kilogram-Kelvin (metric) or British thermal units per pound-degree Rankine (imperial). In addition to offering entropy and enthalpy for steam just before and at the moment of evaporation, as is the case with density and volume, the table also provides these values for steam that has already evaporated.
