HI I have a couple of questions pertain to the sample test 1 could you please help me ?

I am working on problem 3 .

This is what I got so far.

I know that the boundary work will be M*P(v2-v1)

because pressure is constant .

OK, so they give me pressure 150 psi

and X=.8 SM. Therefore I can find my V/me =2.4156 ft ^3/lbm

Therefore I can find my mass =V/(V/m)= 4.13976 lbm

Now I am to go to state 2 where pressure = 150 psi and I am a saturated vapor therefore I need to take the value of vg on my table =3.0150 ft^3/lbm.

NOW this is where the confusion comes in is my final temp tsat because I am still in a mixture ????? How do I find final temp?

Please help......
