ME203 Midterm 2 Name: Section # Problem 2 (45 points): One kilogram of water is enclosed inside a container. Initially, the water has a temperature of 50"C and a specific internal energy of 1500 kJ/kg. The water undergoes the following processes: l-+2: quasi-equilibrium process ends with P2:5 bar and xz: 0.5; 2-+3: constant pressure end with Tf250"C; Do the following: 1 . Sketch the process 1 +3 on a T-v diagram ( 1 0 points) 2. Determine P1 (5 points) 3 . Determine
