Hello, please help me solve this exercise while clearly explaining how each step was found so I can prepare for my exam. You might need thermodynamic tables for water!
A piston-cylinder assembly containing 100 g of water. Initially, the piston, having a surface of 0.2 m^2, is 1 m from the position of the spring (the spring not being attached to the piston). Water is in a two-phase liquid-vapor state with a titer of 0.8 and a pressure of 100 kPa. The system is then heated until a final pressure of 200 kPa is obtained.
Answer the following questions by completing a table of thermodynamic states. (Table should contain: state, temperature, pressure, mass, specific volume, volume, x for composition).
a) What is the temperature of the system when the piston reaches the spring?
b) What is the displacement of the spring (k=1000 kN/m) when the system has reached the final pressure of 200 kPa?
(Hint: You can hypothesize that the mass of the piston is negligible when establishing a force balance).
c) What is the final temperature of the system?
d) Represent these state evolutions on a P-v projection.
e) Evaluate the total work interaction associated with this process.
