0.5 kg of water initially at 400 kPa and 0.3 m3/kg is contained within a piston-cylinder device fitted with retractable stops (initially retracted) so that the water supports the weight of the piston and the force of the atmosphere (state 1). The water is heated until it reaches the saturated vapor state (state 2). The stops are then engaged with the piston against the stops, and the water is further heated until the pressure reaches 600 kPa (state3).
a) Determine the phase and temperature of each state
b) What is the volume capacity of the cylinder with stops engaged?
c) Sketch the process on a P-v and T-v diagram, labelling the states and drawing a line from state 1 to 2 to 3 to represent the process. For the T-v diagram, label the axes with the T and v values of each state. For the P-v diagram, label the axes with the P and v values of each state. Include the saturation dome (saturation lines) in your sketch.
