Compressibility in gas
WebThe calculation in figure 1 shows a compressibility factor of 0.7. In this case, assuming a compressibility factor of 1.0 when it is really 0.7 would result in a Cv calculation that would be about 20 percent high. When the compressibility factor decreases, so does the calculated required valve capacity (C v or K v). Figure 1. Web1.3.2 Gas Compressibility. The isothermal gas compressibility is defined as the change in relative volume per unit pressure drop at a constant temperature: (1.163) C g = − 1 V ( …

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 a useful thermodynamic property for modifying the ideal gas law to …
