Q.6 – Q.10 carry two marks each.
Zm and Zn are the compressibility factor of the gases M and N under the given operating conditions, respectively. The relation between Zm and Zn is
The volumetric properties of two gases M and N are described by the generalized compressibility chart which expresses the compressibility factor (Z) as a function of reduced pressure and reduced temperature only. The operating pressure (P) and temperature (T) of two gases M and N along with their critical properties (Pn, Tn) are given in the table below.
| Gas | P (bar) | T (K) | Pn (bar) | Tn (K) |
|---|---|---|---|---|
| M | 25 | 300 | 75 | 150 |
| N | 75 | 1000 | 225 | 500 |
Zm and Zn are the compressibility factor of the gases M and N under the given operating conditions, respectively. The relation between Zm and Zn is
