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.
