Wet steam at 15 bar is throttled adiabatically in a steady-flow process to 2 bar. The resulting stream has a temperature of 130°C. What are the temperature and quality of the wet steam? Calculate the change of entropy of the steam as a result of the process. It is important to note that a throttling process is where the change of enthalpy is zero (that is, AH = 0). Temperature ~ 198 °C and the quality of 96.76%. AS = 0.8708 kJ/kg-K
