The Lee-Kesler correlation functions for this quantity can be used to directly calculate the Lee-Kesler correlation functions for the 2nd virial coefficient.
The Lee-Kesler correlation functions for this quantity can be used to directly calculate the Lee-Kesler correlation functions for the 2nd virial coefficient. Those correlations approximate this quantity by providing a linear relationship between it and the Pitzer acentric factor. Generalized charts for this quantity plot curves of iso-reduced temperature on a graph with reduced pressure as the x-axis and this quantity as the y-axis. At the critical point, this quantity is equal to 3/8 according to the Van der Waals equation. At the Boyle temperature, this quantity is approximately 1. This quantity is calculated using a power series in either the molar density or pressure by the virial equation. Ideal gasses have a value of 1 for, FTP, what quantity defined as the ratio of PV to nRT and commonly symbolized Z.
