Steam Chart



Steam and water properties using the 1967 IFC Formulation for Industrial Use, and Condenser performance using the HEI (Heat Exchange Institute) method. Steam for the iPhone and iPod touch calculates the thermodynamic properties of water and steam for subcooled (compressed liquid), saturated, superheated, and supercritical conditions.

All of the properties of steam are interrelated. From any one known value you can determine any of others. These relationships are all displayed on a table called the Properties of Saturated Steam, or simply, the Steam Tables.

For any given pressure, you can read:

  • the steam temperature
  • the heat of the saturated liquid
  • the latent heat of the steam
  • the total heat of the steam
  • the specific volume of the saturated liquid
  • the specific volume of saturated steam.

The following measurements are expressed in imperial values. To view these pages in SI metric units, click here.

If you know that you need a temperature of 307 degrees F, the table tells you that you need to pressurize the system to 60 psig. If you have a 15-psi steam supply, the tables tell you that you have 945 Btu/lb. of heat energy available to do work.

1)1 bar abs = 0 bar gauge = 100 kPa abs = atmospheric pressure

  • Vacuum steam is the general term used for saturated steam at temperatures below 100°C.

Example - Boiling Water at 100 oC, 0 bar(100 kPa) Atmospheric Pressure

At atmospheric pressure (0 bar g, absolute 1 bar ) water boils at 100 oC and 417.51 kJ of energy is required to heat 1 kg of water from 0 oC to evaporating temperature 100 oC.

Therefore the specific enthalpy of water at 0 bar g (absolute 1 bar ) and 100 oC is 417.51 kJ/kg.
Another 2257.92 kJ of energy is required to evaporate 1 kg of water at 100 oC into 1 kg of steam at 100 oC. Therefore at 0 bar g (absolute 1 bar) the specific enthalpy of vaporation is 2257.19 kJ/kg.

The total specific enthalpy for steam at 0 bar gauge is:

Https://steamcharts.com/

Steam

hs = (417.51 kJ/kg) + (2257.92 kJ/kg)

= 2675.43 kJ/kg

Example - Boiling Water at 170 oC and 7 bar (700 kPa) Atmospheric Pressure

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. In a steam distribution system the pressure is always more than 0 bar gauge.
At 7 bar g (absolute 8 bar) the saturation temperature of water is 170.42 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. According the table 720.94 kJ is required to raise 1 kg of water from 0 oC to saturation temperature 170 oC.
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. The specific enthalpy of vaporization decreases with steam pressure. The evaporation heat is 2046.53 kJ/kg at 7 bar g.

  • Note! The specific volume of steam decreases with increased pressure - and the amount of heat energy distributed by the same volume increase. With higher pressure - more energy can be transferred in a steam distribution system.
