¹⁾ Atmospheric pressure is used for the table except for ²⁾

²⁾ Critical Point - At 3206.2 psia and 705.40^oF the vapor and liquid are indistinguishable. No change of state occurs when pressure increases above the critical point or when heat is added. At the critical point it is no longer referred to water or steam and it is not possible keep the water and steam apart.

1 psi (lb_f/in²) = 6894.8 Pa (N/m²) = 0.06895 bar

Properties of Saturated Steam - SI Units

Note! Gauge Pressure = Absolute Pressure - Atmospheric Pressure

NTP - Normal Temperature and Pressure - is defined as 20^oC (293.15 K, 68^oF) and 1 atm ( 101.325 kN/m², 101.325 kPa, 14.7 psia, 0 psig, 30 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 - water boils at 212^oF. 180 Btu/lb of energy is required to heat 1 lb of water to saturation temperature 212 ^oF.

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

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