WebDetermination ofCompressibility Factor of GasMixtures• Studies of the gas compressibility factors for natural gases of variouscompositions have shown that compressibility factors can be generalizedwhen they are expressed in terms of the following two dimensionlessproperties: • (1) Pseudo-reduced pressure and (2)Pseudo-reduced … In thermodynamics, the compressibility factor (Z), also known as the compression factor or the gas deviation factor, describes the deviation of a real gas from ideal gas behaviour. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure. It is … See more The compressibility factor is defined in thermodynamics and engineering frequently as: $${\displaystyle Z={\frac {p}{\rho R_{\text{specific}}T}},}$$ where p is the … See more In order to read a compressibility chart, the reduced pressure and temperature must be known. If either the reduced pressure or temperature is unknown, the reduced specific volume must be found. Unlike the reduced pressure and temperature, the reduced specific … See more Deviations of the compressibility factor, Z, from unity are due to attractive and repulsive intermolecular forces. At a given temperature and pressure, repulsive forces tend to make the volume larger than for an ideal gas; when these forces dominate Z is … See more The unique relationship between the compressibility factor and the reduced temperature, $${\displaystyle T_{r}}$$, and the reduced pressure, $${\displaystyle P_{r}}$$, was first recognized by Johannes Diderik van der Waals in 1873 and is known as the two … See more There are three observations that can be made when looking at a generalized compressibility chart. These observations are: See more The virial equation is especially useful to describe the causes of non-ideality at a molecular level (very few gases are mono-atomic) as it is derived directly from statistical mechanics: Where the … See more It is extremely difficult to generalize at what pressures or temperatures the deviation from the ideal gas becomes important. As a rule of thumb, the ideal gas law is reasonably accurate up to a pressure of about 2 atm, and even higher for small non … See more WebDetermine the reduced temperature of superheated water vapor at 15.83 MPa and 359.91 C, using the generalized compressibility chart. Assume that the compressibility factor is 0.64. R = 0.4615 kPa·m3/kg·K This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
