WebMay 31, 2024 · Dry saturated steam refers to a partially condensed form of water that occurs at temperatures and pressures where water vapor and liquid water can co-exist. Such conditions accelerate the corrosion rate of surrounding metals. Dry saturated steam occurs when the rate of water vaporization is equal to the rate of its condensation. WebFor steady state conditions, dry saturated steam condenses at constant pressure, and the steam state point moves down the constant pressure line as shown in Figure 2.15.9. Example 2.15.2. This example considers steam condensing from saturation at 2 bar at 120 °C with an entropy of 7.13 kJ/kg K, and an enthalpy of about 2700 kJ/kg.
