Problem 5.85 Compressibility Factors Use the generalized compressibility chart to estimate z for a. nitrogen at -100°C and 10 MPa b. helium at -255°C and 250 atm Reference Materials Physical Property Tables Generalized compressibility factors (Reprinted with permission from Chemical Process Principles Charts, 2nd Edition,by .. Hougen, K. M watson, and R. A. Ragatz, John Wiley & Sons, New York, 1960.) (Based on L. C. Nelson and E. F. Obert, Trans. ASME, 76, 1057(1954).) rt, medium pressures (Based on L. C. Nelson and E. F. Obert, Trans. ASME, 76, 1057(1954).) (Based on L. C. Nelson and E. F. Obert, Trans. ASME, 76, 1057(1954).)Explanation / Answer
compressibility factor for nitrogen at -1000 C & 10 Mpa is 0.72.
