For water, mark each of these states on the p-v, T- v, and the phase (p-T) diagrams. Use 1
bar = 100 kPa.
(a) T = 95 °C and P = 50 kPa
(b) T = 95 °C and P = 1 bar
(c) T = 95 °C and $\vartheta$ = 1 m³/kg
Caution: Be mindful of unit conversions.
Hint #1: This problem is completely based on Table A-2 in the appendix of the book.
Hint #2: We have discussed the T-u diagram extensively in class. These diagrams involve
isobars (constant pressure lines). Use the isobars to locate the states.
The p-u diagrams involve isotherms (constant temperature lines). Use the
isotherms to locate the states.
Hint #3: For part (c), look at the us and ug at the given temperature.
What can you say about the phase at this state?
