Example-Boiling Water at 170 oC, 7 bar Atmospheric Pressure. Steam at atmospheric pressure is of a limited practical use because it cannot be conveyed under its own pressure along a steam pipe to the point of use. At 7 bar g (absolute 8 bar), the saturation temperature of water is 170.42 oC.t atmospheric pressure (0 bar g, absolute 1 bar) , water boils at 100 oC, and 417.51 kJ of energy are required to heat 1 kg of water from 0 oC to its evaporating temperature of 100 oC. Therefore the specific enthalpy of water at 0 bar g (absolute 1 bar) and 100 oC is 417.51 kJ/kg, as shown in the table.
