Generalized Compressibility Chart

Generalized Compressibility Chart - Reduced pressure is the ratio of the actual pressure. On a generalized compressibility chart, the compressibility z z is plotted as a function f = f(pr,tr) f = f ( p r, t r) of the reduced pressure and temperature. Is the same for all gases. 13.12 and 13.15 resulting in the following equations for real gases. At high temperatures (tr > 2), ideal gas behavior can be assumed with good accuracy. Z = pv¯¯¯¯ rt z = p v ¯ r t. Vapor pressure curves for common pure gases. Compare the results of parts (a) and (b) with values obtained from the thermodynamic table or software11. 2.1 and 2.3) is modified for use for real gases by introducing the generalized compressibility factor, which is represented. Web the compressibility factor chart plots the compressibility factor , equal to , where is the volume per mole, versus the reduced pressure for several values of the reduced temperature.

These have been extended [see, e.g.,. It is valid for many substances, especially those that have simple molecular structures. Web the compressibility factor equation can be written as: The ideal gas equation (eqs. Reduced pressure is the ratio of the actual pressure. At very low pressure (pr << 1), gases behave as an ideal gas regardless of temperature. The ideal gas equation (eq. A practical guide to compressor technology, second edition, by heinz p. Values for p c and t c for various substances can be found in table c.12. Z = pv¯¯¯¯ rt z = p v ¯ r t.
