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.

Note! Gauge Pressure = Absolute Pressure - Atmospheric Pressure

NTP - Normal Temperature and Pressure - is defined as air at 20oC (293.15 K, 68oF) and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr)
