Thermodynamics help with entropy

Homework Statement

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

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 - what does the Clapeyron equation tell you?

I figured it out,it was actually very simple, Thanks for the help
