3.32 a) Define the system to be the nitrogen gas. Since a Joule-Thomson expansion is isenthalpic, . Using the pressure enthalpy diagram for nitrogen, Figure 3.3-3, we have ±,±,HT P112 2afa=fH±.±HTTP13520 MPa1530415322K,kJ / kg and then MPa,kJ / kg()====chFrom which we find that T= 90 K, with approximately 55% of the nitrogen as vapor, and 45% as
