In Chapter 4, we learned about the isothermal compressibility, κT, which is defined as. κT is a very useful quantity, as it can be measured for many different substances and tabulated. Also, as we will see in the next chapter, it can be used to evaluate several different partial derivatives involving ... WebThe Compressibility factor for a Real Gas at High Pressure is. The compressibility factor of natural gas (which corrects for the ratio of actual volume to ideal volume) is roughly 0.5% correction in volume per 100 psi of pressure for an orifice meter under normal pressure and temperature conditions. (P+a/V2) (V−b)=RT.
