Note! The specific volume of steam decreases with increased pressure - and the amount of heat energy distributed by the same volume increase.The evaporation heat is 2046.53 kJ/kg at 7 bar g. The specific enthalpy of vaporization decreases with steam pressure. The heat energy (enthalpy of evaporation) needed at 7 bar g to vaporize the water to steam is actually less than required at atmospheric pressure. According the table 720.94 kJ is required to raise 1 kg of water from 0 oC to saturation temperature 170 oC. More heat energy is required to raise its temperature to saturation point at 7 bar g than needed when the water is at atmospheric pressure. In a steam distribution system the pressure is always more than 0 bar gauge.Īt 7 bar g ( absolute 8 bar) the saturation temperature of water is 170.42 oC. Steam at atmospheric pressure is of a limited practical use because it cannot be conveyed by its own pressure along a steam pipe to the points of use. = 2675.43 kJ/kg Example - Boiling Water at 170 oC and 7 bar (700 kPa) Atmospheric Pressure The total specific enthalpy for steam at 0 bar gauge is: Therefore at 0 bar g ( absolute 1 bar) the specific enthalpy of vaporation is 2257.19 kJ/kg. Therefore the specific enthalpy of water at 0 bar g (absolute 1 bar ) and 100 oC is 417.51 kJ/kg.Īnother 2257.92 kJ of energy is required to evaporate 1 kg of water at 100 oC into 1 kg of steam at 100 oC.
