Note Gauge pressure » Absolute pressure + 100 kPa Back to index of Appendices Appendices > APPENDIX 9 Saturated steam is steam that is in equilibrium with heated water at the same pressure (it has not been heated past the boiling point for that pressure). In a steam distribution system the pressure is always more than 0 bar gauge. The tables in this section are reprinted, with permission, from NBS/NRC Steam Tables. H. MILWAUKEE VALVE HAMMONDVALVE Inches Absolute STEAM TEMPERATURE PRESSURE TABLE SATURATED STEAM TEMPERATURES Temperature Gauge Temperature Gauge Temperature Gauge Temperature Gauge Set your preferences for these steam tables. 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.

The following tables of the properties of steam are taken directly from Chapter 5.5.3 of the Heat Exchanger Design Handbook, 1986, by C. F. Beaton. (a) Saturated Steam: Saturated steam is a vapour at the temperature corresponding to the boiling point of the liquid at the given pressure. Set your preferences for these steam tables. 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. Reducing saturated steam temperature while maintaining pressure will cause the steam to condense, even though the temperature may be well above the 212 °F boiling point at 1 atmospheric pressure. Therefore at 0 bar g (absolute 1 bar) the specific enthalpy of vaporation is 2257.19 kJ/kg. Online calculator with Saturated Steam Table by Temperature. Steam sterilization is generally carried out at temperatures between 121°C (250°F) and 134°C (273°F), under 15 psi (0.5 bar) pressure, between 10 and 60 min, depending upon the material and need.

NTP - Normal Temperature and Pressure - is defined as 20 o C ( K, 68 o F) and 1 atm ( kN/m 2, kPa, psia, 0 psig, 30 in Hg, torr) Vacuum steam is the general term used for saturated steam at temperatures. B_02_cont_tbl 7. If the temperature of the steam is increased to 120 0 C at the atmospheric pressure, then it becomes superheated steam. The total specific enthalpy for steam at 0 bar gauge is: 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.

I got Saturated Pressure to work, but can't get saturated Temperature to work. Heat of Saturated Liquid (Column 4). Steam tables Saturated steam - enthalpy, entropy, specific volume, as a function of pressure and temperature. This is the amount of heat required to raise the temperature of a pound of water from 32°F to the boiling point at the pressure and temperature shown. "The DIN 2448 pipe grade corresponds to the EN 10220 pipe grade for this calculation.)" B_02tbl 6. In steam tables, extensive properties at saturated liquid and at saturated vapor for 1 kg of liquid/vapor are given as shown in Table 21.1(a) and Table 21.1(b). A substance, which is in the vapour state in a confined space and is in contact with some of the same substance in liquid state is always at the same temperature as the liquid and is saturated vapour. WARNING: Exposure to steam is hazardous.If not properly controlled, steam can cause property damage, serious bodily injury, or death.
