Thermodynamics help with entropy

  1. Apr 15, 2012 #1
    1. The problem statement, all variables and given/known data

    Is it possible for an adiabatic liquid-vapor separator to separate wet steam at 100 psia, 90 % quality into a saturated liquid stream and a saturated vapor stream both at a pressure greater than 100 psia?

    Ans: (no according to the increase in entropy principle)

    I need to prove this

    3. The attempt at a solution

    I tried proving by using a t s diagram, but I could make any sense of it

    OK, what does it take to move up in the +p-direction on a p-V diagram when all you can have is saturated water, saturated vapor, and a combination of the two?

    If you want to be really sophisticated :smile: - what does the Clapeyron equation tell you?
