1. The problem statement, all variables and given/known data 2. Relevant equations specific volume = volume / mass dryness fraction = mass of vapor / total mass pressure 3. The attempt at a solution part(a) is totally not relevant to part(b) and I finished part (b)i dryness fraction = 0.5244 specific volume = 0.0502 m^3/kg specific internal energy = 1800 KJ/kg Then, I want to use the relationship between the volume of original and final state to final out the pressure. However, I can't use the above information to calculate the answer. Therefore, I want to ask about the question about (b)ii - v. Thanks.
