Water contained in a piston-cylinder assembly undergoes two processes in series (point 1 to point 2 and point 2 to point 3): point 1: T1 = 100°C and P1 = 5bar point 2: 71= 151.9°C and P2 = 5bar and v2 = .300 m³ point 3: 73= 200°C and v3: - Use the thermodynamic tables A.2, A.3, and A.4 to answer the following questions: For questions 1, 3, and 5 choose from: subcooled water, saturated water, saturated liquid, saturated vapor, superheated vapor 1) What is the thermodynamic state of water at point 1: 2- What is the specific volume of water at point 1: 4) What is the quality of water (x) at point 2: 0.300 3) What is the thermodynamic state of water at point 2: 4) What is the pressure of water at point 3: 3) What is the thermodynamic state of water at point 3: (bar) mº kg On paper draw points 1, 2, and 3 on the following P-v and T-v diagrams and show the two processes. Add number values, units, and constant pressure or temperature lines if needed. Specify which table you used to find each state or value.
