2. A Joule-Thomson valves expands steam from 800C and 350 bar to 100 bar. Determine the outlet temperature of the steam assuming steam is: (a) A real fluid following the steam tables in Appendix A.III. (b) A real fluid following the generalized Peng Robinson equation of state (and CP=40J/molK ). Note: You can try to do this by hand, but solving for Z using the PR eqn given T and P requires implicit numerical solution. On top of that, you are trying to find T2, and both Z and the energy balance require it. It makes sense to write a Python script to solve this part of the question. If you do, please upload your *.py or *.ipynb file along with your scanned handwritten work to Learn
