Problem 5. A piston-cylinder assembly contains 0.15 kg of H2O in an initial state where the fluid is saturated steam (saturated vapor). The piston is held in place by a weight that maintains a pressure of 0.4 MPa (400 kPa). a. Find the cylinder volume and temperature at the initial state.b. Starting with the above initial state, a process is performed in which 30 kJ of heat is added to the cylinder to reach the final state. Find the final volume and temperature.c. Consider a second process with the initial state as in Part a., in which heat is removed until there is a liquid-vapor mix with a quality of 0.55. Find the amount of heat removed and the final volume.

Problem 5.
A piston-cylinder assembly contains 0.15 kg of H2O in an initial state where the fluid is saturated steam (saturated vapor). The piston is held in place by a weight that maintains a pressure of 0.4 MPa (400 kPa).
a. Find the cylinder volume and temperature at the initial state.
b. Starting with the above initial state, a process is performed in which 30 kJ of heat is added to the cylinder to reach the final state. Find the final volume and temperature.
c. Consider a second process with the initial state as in Part a., in which heat is removed until there is a liquid-vapor mix with a quality of 0.55. Find the amount of heat removed and the final volume.
