Carbon dioxide (CP = 38 J/mol-K) at 1.5 MPa and 25C is expanded to 0.1 MPa through

Question:

Carbon dioxide (CP = 38 J/mol-K) at 1.5 MPa and 25°C is expanded to 0.1 MPa through a throttle valve. Determine the temperature of the expanded gas. Work the problem as follows:

(a) Assuming the ideal gas law

(b) Using the Peng-Robinson equation

(c) Using a CO₂ chart, noting that the triple point of CO₂ is at -56.6°C and 5.2 bar, and has a heat of fusion, ΔH^fus, of 43.2 cal/g.
