Unformatted text preview: passes through. Assume that normal butane can be represented by a Peng Robinson equation of state. (2) For the liquefaction of nitrogen by Joule Thompson throttling, the inlet to the expansion valve is -122°C and the pressure is 100 bar. The outlet is at one bar. Determine the percentage of nitrogen that liquefies. (3) E&L, 6.2 (b) (ii). That is use the P-R EOS and do the calculation for propane. (4) Design an experiment that would allow you to measure the departure function for internal energy at fixed temperature and pressure. Describe how you would make the measurement. (5) E-L, 7.6 (6) E-L 7.13 (7) E-L 7.18 (8) Use the steam tables to evaluate the entropy departure function for steam at 3.0 MPa and 450°C....
