A wet steam at 20.0 bar with a quality factor of 0.980 leaks through a defective steam trapt and expands to a pressure of 1 atm. The process can be considered to take place in two stages: a rapid adiabatic expansion to 1 atm accompanied by complete evaporation of the liquid droplets in the wet steam, followed by cooling at 1 atm to ambient temperature. AEx may be neglected in both stages. Steam produced in a boiler is frequently "wet"-that is, it is a mist composed of saturated water vapor and entrained liquid droplets. The quality of a wet steam is defined as the fraction of the mixture by mass that is vapor. tA steam trap is a device to purge steam condensate from a system without venting uncondensed steam. Physical Property Tables Temperature After Expansion X Check your interpolation of tabular values. Estimate the temperature of the superheated steam immediately following the rapid adiabatic expansion. i 126 C
