QUESTION:
Problem 25HP
Determine the phase of water at
a. T = 260°C, P = 5 MPa
b. T =−2°C, P = 100 kPa
ANSWER:
Solution 25HP
Part (a)
Step 1 of 2:
We are going to find the phase of water at the given temperature and the temperature range.
The temperature of water T = 260°C
The pressure of water P = 5 MPa
From the table B.11 and B.12
The saturated temperature Tsat = 263.99°C
The critical pressure Psat = 4688.6 kPa = 4.689 MPa
Tsat > T
Psat < P
The state of water is compressed liquid.
