¹⁾ Atmospheric force per unit area is used for the table except for ²⁾

²⁾ Critical Betoken - At 3206.two psia and 705.twoscore^oF the vapor and liquid are duplicate. No modify of country occurs when pressure increases above the critical point or when estrus is added. At the critical point it is no longer referred to h2o or steam and it is not possible keep the h2o and steam apart.

i psi (lb_f/in²) = 6894.8 Pa (N/m^two) = 0.06895 bar

Properties of Saturated Steam - SI Units

Note! Gauge Pressure = Accented Force per unit area - Atmospheric Force per unit area

NTP - Normal Temperature and Pressure - is divers every bit twenty^oC (293.15 K, 68^oF) and i atm ( 101.325 kN/one thousand², 101.325 kPa, 14.vii psia, 0 psig, xxx in Hg, 760 torr)

Vacuum steam is the general term used for saturated steam at temperatures below 100°C.

Example - Boiling Water at 212^oF and 0 psig

At atmospheric pressure - 0 psig - h2o boils at 212 ^oF. 180 Btu/lb of energy is required to heat i lb of water to saturation temperature 212 ^oF.

Therefore, at 0 psig and 212^oF - the specific enthalpy of h2o is 180 Btu/lb.

Another 970 Btu/lb of energy is required to evaporate the 1 lb of water at212 ^oF to steam at 212 ^oF. Therefore, at 0 psig - the specific enthalpy of evaporation is 970 Btu/lb .

The full specific enthalpy of the steam (or heat required to evaporate water to steam) at atmospheric pressure and212 ^oF can be summarized to
