A frictionless piston-cylinder arrangement, shown in the figure, is equipped with stops and contains
0.9 kg of water. Initially, the piston is resting on the stops when the water is at 150°C. Heat is added
and the piston starts to rise when the pressure is 700 kPa and the water is in saturated liquid-vapor
form with quality of 80%. Heat is further added until the temperature reaches 200°C.
Find:
1. Sketch T-v and P-v diagrams with respect to saturation lines and show the states and processes
with directions
2. Determine the total work done during the process, in kJ.
3. Determine the amount of heat transfer during the process, in kJ.
