QUESTION:
Problem 24HP
Give the phase for the following states:
a. CO2 at T = 40°C and P = 0.5 MPa
b. Air at T = 20°C and P = 200 kPa
c. NH3 at T = 170°C and P = 600 kPa
ANSWER:
Solution 24HP
Part (a)
Step 1 of 3:
We are going to find the state of CO2
The temperature T = 40°C
The pressure P = 0.5 MPa
The critical temperature from the table A-2
The critical temperature TC = 304.1 K = 31°C
The critical pressure PC = 7.38 MPa
TC < T
PC > P
The state of CO2 is the superheated vapor state.
Part (b)
