Saturated Water and Steam (Temperature-based), Contd. At atmospheric pressure (0 bar g, absolute 1 bar ) water boils at 100 o C and 417.51 kJ of energy is required to heat 1 kg of water from 0 o C to evaporating temperature. Example - Boiling Water at 100 o C, 0 bar (100 kPa) Atmospheric Pressure.

Vacuum steam is the general term used for saturated steam at temperatures below 100вЊ.Example - Boiling Water at 212 oF and 0 psigAt atmospheric pressure - 0 psig - water boils at 212 oF. Properties of Saturated Steam - SI UnitsNote! Gauge Pressure = Absolute Pressure - Atmospheric PressureNTP - Normal Temperature and Pressure - is defined as 20 oC (293.15 K, 68 oF) and 1 atm ( 101.325 kN/m 2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr) 1 psi (lb f/in 2) = 6894.8 Pa (N/m 2) = 0.06895 bar
