Water vapor initially at 3.0 MPa and 300°C is contained within a piston-cylinder. The water is cooled at constant volume until its temperature is 200°C . The water is then compressed isothermally to a state where the pressure is 2.5 MPa.
a. Locate states 1, 2, and 3 on a T-v and P-v diagram
b. Determine the specific volume at all three states,
c. Calculate the compressibility factor Z at state 1 and comment
d. Find the quality (if applicable) at all three states.
