The volumetric properties of two gases M and N are described by the generalized compressibility chart which expresses the compressibility factor (
) as a function of reduced pressure and reduced temperature only. The operating pressure (
) and temperature (
) of two gases M and N along with their critical properties (
) are given in the table below.Gas | (bar) | (K) | (bar) | (K) |
|---|---|---|---|---|
M | 25 | 300 | 75 | 150 |
N | 75 | 1000 | 225 | 500 |
and
are the compressibility factor of the gases M and N under the given operating conditions, respectively. The relation between
and
